Quality of life in patients with scalp psoriasis treated with calcipotriol/betamethasone dipropionate scalp formulation: a randomized controlled trial
Bibliographic record
Abstract
Abstract Background Psoriasis vulgaris of the scalp has a significant psychosocial impact on individuals affecting their quality of life (QoL). A combination of calcipotriol and betamethasone dipropionate in a formulation suitable for treatment of scalp psoriasis has been developed. Objective To assess the impact of treatment with either calcipotriol plus betamethasone dipropionate scalp formulation or calcipotriol scalp solution on QoL in patients with scalp psoriasis (both within and between treatment groups). Methods This 8‐week, randomized, investigator‐blind study, compared the once‐daily, two‐compound scalp formulation (calcipotriol 50 µg/g plus betamethasone 0.5 mg/g as dipropionate; Xamiol ® , LEO Pharma A/S, Ballerup, Denmark) with twice‐daily calcipotriol scalp solution (50 µg/mL; Daivonex ® , LEO Pharma A/S) in patients with scalp psoriasis of at least moderate severity covering ≥ 10% of the scalp. QoL was assessed (weeks 0, 2, 4, 8) using the 36‐item Short Form Health Survey (version 2; SF‐36v2) and Skindex‐16. Results Treatment with the two‐compound scalp formulation ( n = 207) resulted in significant improvements from baseline on the SF‐36v2 (Physical Component Summary, P = 0.005, week 8; Mental Component Summary, P < 0.05, weeks 2, 4, 8). A significant change from baseline in the calcipotriol scalp solution group ( n = 105) was seen only on the Mental Component Summary ( P = 0.04, week 8). Change from baseline in Skindex‐16 was significantly in favour of the two‐compound scalp formulation. Change was significant on both total score and individual scales. Conclusion The two‐compound scalp formulation was superior to calcipotriol scalp solution in improving QoL in patients with scalp psoriasis. Conflict of interest declaration J.P.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
