Fig. 2: Kaplan–Meier cumulative survival curve for all-cause workforce exit among workforce active persons newly diagnosed with Parkinson’s disease and matched controls by sex and highest attained education.
From: Time to workforce exit after a Parkinson’s disease diagnosis
a Survival distributions differed significantly between PD cases and controls for both sexes (log-rank tests, both P < 0.001), but there were no significant differences between females and males within the PD case or control groups (P = 0.545 and 0.433, respectively). The median workforce survival was 42.0 (95% CI: 38.4–45.6) months in female PD patients (events: 816, censored: 247) and 45.0 (95% CI: 41.9–48.1) months in male PD patients (events: 1525, censored: 486). The median survival in the control groups were 66 (95% CI: 63.0–69.0) months in females (events: 2773, censored: 1476) and 66 (95% CI: 64.0–68.0) months in males (events: 5215, censored: 2819). b The median workforce survival was 38.0 (95% CI: 35.2–40.8) months in the PD group with lower education (events: 1538, censored: 401) and 52.0 (95% CI: 48.0–55.9) months in the PD group with higher education (events: 803, censored: 322). The survival in the control groups were 62.0 (95% CI: 60.2–63.8) months in the lower (events: 5638, censored: 2685) and 80.0 (95% CI: 76.3–83.7) months in the higher (events: 2350, censored: 1582) education group. Survival distributions tested using log-rank tests, all P < 0.001. Lower education: upper secondary school or lower, higher education: post-secondary school or higher.
