These findings suggest that at PDAI ≥ 7, every incremental increase in PDAI had a smaller detrimental impact on QoL. For the ABSIS, there was no significant difference in slopes before and after a given score, along with a higher P-value overall. Our results support previous findings 6 that the PDAI is superior to the ABSIS at capturing disease severity, especially at the lower end of disease activity (Figure 1c,d).To significantly improve QoL for patients with mucosal and nonmucosal PV, complete disease clearance may be necessary. Small amounts of worsening activity have an increasingly significant impact on QoL at the lower end of the spectrum. Above mild levels of activity, increasing activity has linear but detrimental smaller effects on QoL. The findings for patients with mucosal PV further support this, likely because oral erosions are painful and impact eating. Consistent with prior findings, 2 the Skindex-S best correlates with PDAI score in all patients.A notable limitation of this study is that our population had milder disease, with a median PDAI of 6Á75 and ABSIS of 11Á75. However, we are still able to show a change in QoL as the PDAI decreases, even at lower PDAI levels. Our findings have important clinical implications in determining appropriate outcomes for therapies. 7 Unlike dermatomyositis and systemic lupus erythematosus, 4 in patients with PV, complete clearance should be the goal.
