Baricitinib response pattern by baseline nail involvement in children under 12 with alopecia areata

Representative baseline nail changes and cumulative incidence of SALT ≤20 by baseline nail-involvement status.(a) Subtle fingernail pitting; the inset shows an enlarged view of the affected nail.(b) Surface roughening with longitudinal ridging involving multiple toenails.(c) Cumulative incidence of the first recorded SALT score ≤ 20 through week 36 according to baseline nail involvement.Permanent baricitinib discontinuation before response was treated as a competing event.Shaded areas indicate pointwise 95% CIs, and the vertical dashed line marks week 24.Numbers below the x-axis indicate participants at risk.CI, confidence interval; SALT, Severity of Alopecia Tool.(a) (c) (b)
