Relevant conflicts of interest/financial disclosures: The present study is a secondary analysis of the database of a clinical trial, CALM-PD, and its extension study, CALM Cohort, which were sponsored by Pharmacia Corporation (Peapack, NJ) and Boehringer Ingelheim (Ingelheim, Germany). In January 2001 Pharmacia approved an investigator (Michael A. Schwarzschild)–initiated proposal to introduce an add-on caffeine questionnaire to CALM-PD subjects to test our prespecified hypotheses that higher caffeine consumption is associated with lower rates of dyskinesia development and/or disease progression. Neither Pharmacia nor Boehringer Ingelheim provided funding for or otherwise supported or participated in the present study. Anne-Marie A.
