Litšebeliso tsa Lipalopalo Bophelong
Pendahuluan
Lipalopalo ke lekala la mahlale le shebaneng le pokello, tlhahlobo, tlhaloso, nehelano le tlhophiso ea lintlha. Lefapheng la bophelo bo botle, lipalo-palo li bapala karolo ea bohlokoa ho utloisiseng mekhoa, ho sibolla likamano le ho etsa liqeto ho latela lintlha tse seng li ntse li le teng. Tšebeliso ea lipalo-palo tlhokomelong ea bophelo bo botle ha e thuse feela ho fumaneng le ho phekola, empa hape le ho rala leano la bophelo bo botle, taolo ea mafu le ho lekola katleho ea mekhoa ea bongaka.
Karolo ea Bohlokoa ea Lipalo-palo Bophelong
1. Lipatlisiso tsa Bongaka
Lipatlisiso tsa bongaka li hokahane ka mokhoa o ke keng oa aroloa le lipalo-palo. Litekong tsa bongaka, lipalo-palo li sebelisoa ho rala liteko, ho fumana boholo bo loketseng ba lisampole, le ho toloka liphetho ka tsela e se nang leeme. Mekhoa ea liteko tsa bongaka, joalo ka liteko tse laoloang ka mokhoa o sa reroang (RCTs), e hloka kutloisiso e felletseng ea tlhahlobo ea lipalo-palo ho netefatsa liphetho tse nepahetseng le tse tšepahalang.
2. Thuto ea mafu a seoa
Epidemiology ke thuto ea kabo ea mafu ka har'a baahi le lintlha tse khethollang kabo eo. Lipalopalo li sebelisoa ho sekaseka lintlha tsa epidemiological, ho hakanya ho ata ha mafu le ho ata ha 'ona, le ho utloisisa lintlha tse kotsi. Ka ho sebelisa mekhoa ea lipalo-palo e kang ho khutlela morao ha logistic le tlhahlobo ea ho pholoha, litsebi tsa epidemiology li ka khetholla likamano tsa sesosa le ho etsa likhakanyo mabapi le ho ata ha mafu.
3. Lipalopalo tsa baeloji
Biostatistics ke lekala le ikhethileng la lipalo-palo tse sebelisetsoang ho araba lipotso tsa baeloji le bophelo bo botle. Litsebi tsa biostatistics li hlahisa mekhoa e mecha ea ho rala lithuto le ho sekaseka lintlha lipatlisisong tsa bongaka. Li thusa bafuputsi ba bongaka ho etsa liqeto tse thehiloeng ho lintlha tse bokelletsoeng ka sepheo sa ho ntlafatsa bophelo bo botle ba sechaba.
Litšebeliso tse Ikhethang tsa Lipalopalo Bophelong
1. Ho rala le ho hlahloba Mananeo a Bophelo bo Botle ba Sechaba
Bophelong ba sechaba, lipalo-palo li sebelisoa ho rala le ho lekola mananeo a bophelo bo botle. Lipotso le liphuputso hangata li sebelisoa ho bokella lintlha mabapi le mekhoa ea bophelo bo botle, phihlello ea lits'ebeletso tsa bophelo bo botle, le boemo ba bophelo bo botle ba baahi. Lintlha tsena li hlahlojoa ho fumana litlhoko tsa bophelo bo botle ba sechaba le ho lekola katleho ea mananeo a bophelo bo botle.
2. Tlhahlobo ea Genomics le Big Data
Phetoho theknolojing ea genomic e hlahisitse lintlha tse ngata tse tsejoang e le "big data." Lipalopalo li bohlokoa haholo ho sebetsaneng le ho sekaseka lintlha tsena ho khetholla mefuta e fapaneng ea liphatsa tsa lefutso e amanang le mafu a itseng. Mekhoa ea lipalo-palo e kang ho bokellana le ho kopanya e sebelisoa ho utloisisa ho rarahana ha lintlha tsa genomic le ho khetholla mekhoa ea bohlokoa ea liphatsa tsa lefutso.
3. Lithuto tsa Sehlopha le Taolo ea Nyeoe
Lithuto tsa sehlopha le lithuto tsa taolo ea linyeoe ke meralo e tloaelehileng ea lithuto tsa epidemiological e sebelisetsoang ho hlahloba kamano pakeng tsa ho pepesehela ho itseng le liphello tsa bophelo bo botle. Thutong ea sehlopha, sehlopha sa batho ba arolelanang tšobotsi e itseng se lateloa ha nako e ntse e ea ho bona liphello tsa bophelo bo botle. Thutong ea taolo ea linyeoe, sehlopha sa batho ba nang le boemo bo itseng se bapisoa le sehlopha se se nang boemo boo ho batla liphapang tsa ho pepesehela kapa litšobotsi tse ling. Mekhoa e nepahetseng ea tlhahlobo ea lipalo-palo e sebelisoa ho lokisa liphetoho tse ferekanyang le ho bala likotsi tse amanang kapa likarolelano tsa menyetla.
4. Taolo le Thibelo ea Mafu a Tšoaetsanoang
Lipalopalo le tsona li bapala karolo ea bohlokoa taolong le thibelong ea mafu a tšoaetsanoang. Mehlala ea lipalo e thehiloeng ho data ea epidemiological e sebelisoa ho bolela esale pele ho qhoma ha mafu le ho lekola tšusumetso ea mekhoa ea bophelo bo botle ba sechaba joalo ka ente. Ho etsa mohlala oa lipalo-palo ho nolofalletsa baetsi ba liqeto ho ntlafatsa mehloli le ho kenya tšebetsong mehato e sebetsang ea thibelo.
5. Tlhahlobo ea Kotsi le Polokeho ea Lithethefatsi
Lipalopalo li bohlokoa ha ho hlahlojoa kotsi le polokeho ea lithethefatsi. Tlhahlobo ea lipalo-palo e sebelisetsoa ho lekola litla-morao tse ka bang teng tsa lithethefatsi le ho fumana melemo le likotsi tsa tšebeliso ea tsona. Liteko tsa kliniki tsa Mokhahlelo oa III, mohlala, li kenyelletsa tlhahlobo e rarahaneng ea lipalo-palo ho netefatsa hore moriana o bolokehile ebile o sebetsa pele o ka amoheloa ke mekhatlo ea taolo.
Mekhoa ea Lipalo-palo Bophelong
1. Tlhahlobo e hlalosang
Tlhahlobo e hlalosang ke mohato oa pele oa ho utloisisa lintlha tsa bophelo bo botle. Lipalopalo tse hlalosang tse kang karolelano, bohareng, mokhoa, le ho kheloha ho tloaelehileng li sebelisoa ho akaretsa le ho hlalosa lintlha. Lipono tsa lintlha tse kang li-bar graph, li-histogram, le li-boxplot li thusa ho khetholla lipaterone le lintho tse sa tloaelehang tse fumanehang ho lintlha.
2. Tlhaloso ea Lipalo-palo
Teko ea lipalo-palo e sebelisoa ho akaretsa ho tloha ho data ea sampole ho ea ho baahi ba bangata. Teko ea khopolo-taba le linako tsa kholiseho ke lisebelisoa tsa bohlokoa ho tekong ea lipalo-palo. Teko ea t-teko, teko ea chi-square, le ANOVA ke mehlala ea liteko tsa lipalo-palo tse sebelisoang khafetsa lipatlisisong tsa bophelo bo botle ho fumana hore na liphapang tse bonoang li bohlokoa ka lipalo-palo.
3. Phetoho le Mohlala oa Lipalopalo
Ho khutlela morao le ho etsa mohlala oa lipalo-palo ho sebelisoa ho utloisisa likamano lipakeng tsa liphetoho tse fumanehang tlhahisoleseling ea bophelo bo botle. Tlhahlobo ea ho khutlela morao ka mola e sebelisoa ho etsa mohlala oa kamano pakeng tsa phetoho e le 'ngoe e ikemetseng le phetoho e le 'ngoe e itšetlehileng ka eona, ha ho khutlela morao ka logistic ho sebelisoa ha phetoho e itšetlehileng ka eona e le binary. Tlhahlobo ea li-multivariate e lumella bafuputsi ho fetola li-variable tse ikemetseng tse ngata le taolo bakeng sa li-variable tse ferekanyang.
4. Tlhahlobo ea ho Pholoha
Tlhahlobo ea ho pholoha e sebelisetsoa ho sekaseka lintlha tsa nako le ketsahalo, joalo ka nako ho tloha tlhahlobong ho isa lefung kapa nako ea ho khutla ha lefu. Meetso ea Kaplan-Meier le mehlala ea likotsi tse lekanang tsa Cox ke lisebelisoa tse tloaelehileng tlhahlobong ea ho pholoha ho hakanya mesebetsi ea ho pholoha le ho khetholla lintlha tse susumetsang nako ho fihlela ketsahalo e itseng.
Qetello
Lipalopalo ke motheo oa lipatlisiso le mekhoa ea tlhokomelo ea bophelo bo botle. Ka ho sebelisa lipalo-palo, litsebi tsa tlhokomelo ea bophelo bo botle li ka etsa liqeto tse betere, tsa rala mekhoa e sebetsang ea ho kenella, 'me tsa lekola mekhoa ea bongaka ka tsela e se nang leeme le ea saense. Tsebo ea lipalo-palo ke ea bohlokoa boitekong bo tsoelang pele ba ho ntlafatsa bophelo bo botle ba sechaba le polokeho. Nakong e tlang, ka tsoelo-pele ea theknoloji le pokello ea lintlha e ntseng e rarahana, karolo ea lipalo-palo tlhokomelong ea bophelo e tla ba ea bohlokoa le ea bohlokoa haholoanyane.
