AB To  understand  further  the  design  of  a  case–control  study,  and  why  the  odds  ratio  from  a  case–control  study  estimates  the  incidence  rate  ratio,  consider  first  the  occurrence  of  a  particular  disease  within  an  underlying  population  that  gives  rise  to  the  cases.  This  underlying  cohort  is  sometimes  called  the  source  population.  At  the  start  of  follow-up,  all  subjects  are  disease-free;  P  people  are  exposed  and  Q  are  not.  After  following  the  cohort  for  t  years,  A  of  the  P  exposed  and  B  of  the  Q  unexposed  subjects  develop  disease  (Table  C–1).
