A systematic review 1 including 13 studies with a total of 659 subjects was abstracted in DARE. The pooled relative risk of death was 0.62 (95% CI 0.38 to 1.05). The results are suggestive of a publication bias; studies with a high weight (larger sample size) showing no therapeutic effect and those with a low weight showing an effect. There was heterogeneity between trials.
Another systematic review 2 including 3 high quality randomized, placebo-controlled trials found that corticosteroids improved survival at 28 days in patients with severe alcoholic hepatitis (84.6% vs 65.1%, p=0.001).
Comment: The quality of evidence is downgraded by possibility of reporting bias.
