definition of predictive or prognostic research and explain! help me pls.. tnx..




Sagot :

 Prognosis simply means foreseeing, predicting, or estimating the probability or risk of future conditions; familiar examples are weather and economic forecasts. Predicting outcomes is not synonymous with explaining their causePrognostic studies require a multivariable approach to design and analysisThe best design to address prognostic questions is a cohort studyHope it helps!
