“…However, more figures (total 32) potentially increase complexity, particularly if the tool were to be used by nonspecialist field workers. We confirmed with BASP authors that neither ICC nor kappa statistics were used to test its reliability, and found the percentage method used in the original publication [3] to inflate agreement in our study. Formal statistics should be considered for future BASP studies, which could also compare reliability with the adapted HNC.…”

“…Then the examination of the same 16 men was repeated randomly by the same staff members but using the adapted HNC. No validated training time has been published as adequate for the use of alopecia classification tools; therefore, we chose 15 min as was used in the most recent classification – the BASP study [3]. …”

“…Hamilton’s original classification [1] was modified to create the Hamilton-Norwood classification (HNC) [2] which is still the most commonly used classification for PHL severity assessment. An impressive collaboration yielded the most recent, the basic and specific (BASP) classification, which can be used for both genders and estimates hair density [3]. …”

Background: The Hamilton-Norwood classification (HNC) is used to assess the severity of pattern hair loss (PHL). Conflicting associations between PHL and cardiovascular disease (CVD) have been reported from studies that used different methods to assess alopecia severity. No classification including the HNC has been validated for population studies. We aimed to simplify the HNC, produce the adapted HNC and test its reliability for use in population studies. Methods: Identifying vertex alopecia as distinct allowed for a simpler alignment of alopecia figures where scores 4V and 5V in the adapted HNC replace IV and V in the original HNC. The two classifications were to be used by twelve of our staff (secretaries, nurses, dermatology trainees and dermatologists) to evaluate 16 men with PHL. Observer agreement was estimated using intraclass correlation coefficient (ICC) and a percentage method duplicated from the recent basic and specific (BASP) classification. Results: The ICC improved with the adapted HNC when assessed by both the nurses/secretaries (from 0.47 to 0.61) and dermatology residents/consultants (from 0.68 to 0.76). Agreement using the BASP percentage method for dermatologists was 62–69% for the original and 93–100% for the adapted HNC. Conclusions: The adapted HNC increased reliability at various staff levels, making it suitable for epidemiological studies; its use in future studies could help elucidate the association between PHL and CVD.

“…In this study, we used the basic and specific (BASP) classification, which can describe variable clinical patterns (Fig 1). 17 This classification provides a precise description of FPHL in Asian men, a condition uncommon in white men, 14,16 and may be applied to both male and female patients.…”
