Change From Baseline in Severity of Alopecia Tool (SALT) Score at Week 24
Query!
Assessment method [1]
0
0
SALT is a quantitative assessment of alopecia areata (AA) severity based on the scalp hair loss. Score range: 0-100%. Higher score indicates more severe disease. Change from baseline is defined as the baseline value minus the value at a specific visit. Positive change from baseline signifies an improvement. Baseline is defined as the last measurement prior to first dosing (Day 1).

0
An AE (non-serious and serious) was any untoward medical occurrence in a participant who received study treatment without regard to possibility of causal relationship. Any such events with initial onset or increasing in severity after the first dose of study treatment were counted as treatment-emergent Adverse Event (TEAE). Treatment-related TEAE were determined by investigators. Arms end with "withdrawal Segment" and "retreatment segment" described the same population while in different treatment segment .The reason why count on PF-06700841 differ by 1 participant is that 1 responder directly entered the retreatment segment and skipped the withdrawal segment.

Change From Baseline in Severity of Alopecia Tool (SALT) Score at Week 24 -AT/AU Participants
Query!
Assessment method [1]
0
0
SALT is a quantitative assessment of alopecia areata (AA) severity based on the scalp hair loss. The SALT score can vary from 0 to 100%, with higher scores representing increasing severity of disease. Change from baseline is defined as the baseline value minus the value at a specific visit. Positive change from baseline implies an improvement. Alopecia totalis (AT): derived as SALT score = 100% at baseline only. Alopecia universalis (AU): derived as SALT score = 100% and both eyelash and eyebrow assessments were "none" at baseline.

SALT is a quantitative assessment of alopecia areata (AA) severity based on the scalp hair loss. A SALT 30 response is a 30% or greater reduction from baseline in SALT score. The SALT score can vary from 0 to 100%, with higher scores representing increasing severity of disease. The analysis was done using FAS (full analysis set) based on Non-responder imputation (ie. set missing values to be non-responsive) data. The 90% CI was calculated using Chan and Zhang method.
