From: Irritable bowel syndrome and Parkinson’s disease risk: register-based studies
Standardized survival function and confidence interval for Parkinson’s disease (PD) comparing individuals with irritable bowel syndrome with those without in SALT Swedish twins. Standardized survival functions of PD were estimated and plotted using regression standardization after fitting the multivariable adjusted Cox model.
