Table V.

Results from the cohort study for the risk of recurrent VTE related to glucocorticoid use at the day of the first venous thromboembolism. All 2547 patients with a first VTE from the MEGA Study (the Netherlands, 1999–2004) who were linked to the Stichting Farmaceutische Kengetallen (SFK) data register were included in these analyses.

Oral glucocorticoids	Observation years	Recurrent events	IRR per 1000 person‐years (95% CI)	HR (95% CI)	HR (95% CI)*
