Reduced incidence of Crohn's disease in systemic sclerosis: a nationwide population study.

ABSTRACT:

Background

To date, there has been no studies to evaluate the incidence of Crohn's disease in systemic sclerosis patients. The goals of this study were to evaluate the incidence of Crohn's disease and its relationship with sex and age in patients with systemic sclerosis.

Methods

We enrolled patients with systemic sclerosis and controls from Taiwan's Registry of Catastrophic Illness Database and National Health Insurance Research Database. Every systemic sclerosis patient was matched to at most three controls by sex, age, month and year of initial diagnosis of systemic sclerosis. The standardized incidence ratio (SIR) of Crohn's disease in systemic sclerosis patients, and 95% confidence interval (95% CI) were calculated. Cox hazard regression was used to calculate the hazard
