Two models estimating odds ratios, comparing odds of being a woman between groups. As was expected, LRRK2 PD were more likely to be women than idiopathic PD (OR, SE: 1.71, 1.10–2.66; p=0.017). Although the odds of being a woman were not different between GBA PD and idiopathic PD (OR, SE: 1.17, 0.76–1.81; p=0.473) or GBA PD and LRRK2 PD (OR, SE: 0.69, 0.39–1.19; p=0.180), severe GBA PD were more likely to be women than both idiopathic PD (6.54, 2.13–20.07; p=0.001), LRRK2 PD (3.83, 1.19–12.34; p=0.025), and even mild GBA PD (6.35, 1.90–21.17; p=0.003).
