| The case definition is adequate with independent validation; Consecutive or obviously representative series of cases; Community controls; Controls with no history of disease (endpoint); Cases and controls with comparable ages and comparability on any other factors; Ascertainment of exposure using secure records (eg surgical records) or structured interviews with blinding to case/control; Ascertainment of exposure using the same method for cases and controls; Ascertainment of exposure with non-response rate for both groups. | |||||||||
