Selection principles

The bibliographies focus on adverse events (AEs) and the safety profile of 5-alpha reductase inhibitors. Some studies focus primarily on AEs, while others are trials which include both efficacy and safety data. Studies which focus exclusively on efficacy, or give only cursory attention to AEs, are generally excluded from the bibliographies. Trials of new products or techniques such as topical solutions or mesotherapy are generally not included.

The bibliographies aim to include all papers on the topic irrespective of their conclusions. There are papers that report null results, those that conclude finasteride has an acceptable safety profile, and those that express skepticism about the validity of ‘post-finasteride syndrome.’

Conference abstracts in the main bibliography appear in a subgroup within each year, e.g., ‘2022 abstracts’. Abstracts generally report early results, and have not gone through a standard peer review process.
