1 Seasonal variation in flares of inflammatory bowel disease
James D. Lewis, Faten N. Aberra, Gary R. Lichtenstein, Warren B. Bilker, Colleen Brensinger, Brian L. Strom  Gastroenterology  Volume 126, Issue 3, Pages (March 2004) DOI: /j.gastro

2 Figure 1 Seasonality of flares within the cohort of Crohn’s disease patients. Gastroenterology  , DOI: ( /j.gastro )

3 Figure 2 Seasonality of flares within the cohort of ulcerative colitis patients. Using winter as the reference category, only spring had a slightly higher rate of flare of disease (OR = 1.13, 95% CI: 1.05–1.23). Gastroenterology  , DOI: ( /j.gastro )

4 Figure 3 Time from first flare to second flare among patients with Crohn’s disease who experienced more than 1 flare. Each bar represents a period of 100 days. The first bar represents the period from day 101 to 200. There is no bar for the period from day 1 to 100 because our algorithm required a minimum of 122 days between prescriptions to identify a new flare. Gastroenterology  , DOI: ( /j.gastro )
