Sensitivity: lub peev xwm ntawm kev sim kom raug txheeb xyuas cov neeg mob uas muaj tus kab mob Qhov tshwj xeeb: lub peev xwm ntawm kev sim kom raug txheeb xyuas cov neeg tsis muaj tus kab mob. Qhov zoo tiag tiag: tus neeg muaj tus kab mob thiab qhov kev kuaj pom zoo. Qhov tsis zoo tiag tiag: tus neeg tsis muaj tus kab mob thiab qhov kuaj pom tsis zoo.
Koj txhais li cas rhiab thiab tshwj xeeb?
Qhov rhiab ntawm qhov kev ntsuam xyuas qhia txog qhov tshwm sim uas qhov kev tshuaj ntsuam xyuas yuav ua tau zoo ntawm cov neeg uas muaj kab mob Piv txwv li, qhov tshwj xeeb ntawm qhov kev sim qhia txog qhov tshwm sim ntawm qhov kev tshuaj ntsuam xyuas yuav tsis zoo rau cov uas qhov tseeb, tsis muaj kab mob.
Dab tsi yog qhov txaus siab thiab qhov tshwj xeeb?
Rau qhov kev sim kom muaj txiaj ntsig, kev nkag siab + qhov tshwj xeeb yuav tsum yog tsawg kawg yog 1.5(ib nrab ntawm 1, uas tsis muaj txiaj ntsig, thiab 2, uas zoo meej). Prevalence cuam tshuam rau kev kwv yees qhov tseem ceeb. Qhov tsawg dua qhov pretest probability ntawm ib qho mob, qhov qis dua qhov ntsuas qhov ntsuas.
Koj xaiv li cas ntawm qhov rhiab thiab qhov tshwj xeeb?
Sensitivity=TP/(TP+FN). Qhov tshwj xeeb qhia tias feem pua ntawm cov neeg uas tsis muaj tus mob muaj qhov tsis zoo ntawm qhov kev xeem. Qhov kev ntsuam xyuas tshwj xeeb yog qhov zoo ntawm qhov tsis suav nrog cov neeg feem coob uas tsis muaj tus mob.
94% rhiab heev txhais li cas?
Qhov tshwj xeeb ntawm kev ntsuas yog 94%, uas txhais tau tias 94% ntawm cov neeg tsis muaj Kab Mob A yuav kuaj tsis zoolossis 6% ntawm cov neeg tsis muaj tus kabmob yuav kuaj pom qhov zoo.
