A new meta-study finds the following:
“Of 34 clinical trials, none had adequate safety reporting, 19 were partially adequate, 12 were inadequate, and 3 reported no adverse events. Funnel plots were asymmetric with a bias toward lower odds ratio for sexual adverse effects, suggesting systematic under detection…”

From Wiki definition: A meta-analysis comprises statistical methods for contrasting and combining results from different studies in the hope of identifying patterns among study results, sources of disagreement among those results, or other interesting relationships that may come to light in the context of multiple studies.[1] Meta-analysis can be thought of as “conducting research about previous research.”
The report is interesting but a Meta Analysis is only as good as the clinical trials it is analyzing. All studies have its advantages and pitfalls. If adverse or sexual side effects were being examined, I question why other (much larger and comprehensive clinical trials) of finasteride 5mg was excluded.
