RISK FACTOR STUDIES OF AGE-AT-ONSET IN A SAMPLE ASCERTAINED FOR PARKINSON DISEASE AFFECTED SIBLING PAIRS: A CAUTIONARY TALE

Risk factor studies of age-at-onset in a sample ascertained for Parkinson disease affected sibling pairs: a cautionary tale

Abstract An association between exposure to a risk factor and age-at-onset of disease may reflect an effect on the rate of disease occurrence or an acceleration of the disease process.The difference in age-at-onset arising from case-only studies, however, may also reflect secular trends in the prevalence of exposure to the risk factor.Comparisons o
