. Further refinement could not be made. Bokovac and Makše speculated with age ranges or AGA classification data not present in the comparative data.

The wide-ranged "31-53%" made reference to the numeric estimation previously made by the authors of the preliminary observation of 41 men admitted for COVID-19, published in the Journal of Cosmetic Dermatology, 5 for "clinically significant AGA" (HNS=3-7) on COVID-19 men aged 23-79 compared to a similar population. The estimation was not for "HNS=2-7" as Bokovac and Makše assumed. The comparison with HNS 2-7 was present in the supplement, specifically, and in detail, check Table 1 . Attempts to convert two different scales is intrinsically limited. For example: how could "vertex-only" be converted to HNS=3v or HNS=5? HNS has "3v" and "5" depicted with frontal involvement (not vertex-only). It is advisable to use the RAW data with different datasets that used the HNS. For example: in a study from India, 100% of the hospitalized patients due to COVID-19 had HNS=2-7 (raw data available at were computed in Severi numbers of the lower part of the table). Madrid COVID-19 data did not classify 3 and 4 into subcategories, and Severi data did not show the exact HNS scores.
