Gupta et al1 report the results of a systematic review and meta-analysis comprising 4 randomized controlled clinical trials of lifestyle modifications, measuring its effects on the IIEF-5 (International Index of Erectile Function [not “Dysfunction,” as repeatedly reported in the article]) score in 597 patients with erectile dysfunction at baseline. The authors found that, after a follow-up lasting 2 to 24 months, the lifestyle modifications were associated with an improvement of 2.4 points in the IIEF-5 score.
