Our aim was to compare 20% with 10% to 5% incremental regimens in narrowband UVB phototherapy.Study patients
The study included patients with psoriasis (N = 191) with Fitzpatrick skin phototypes II and III.Results
Occurrence of erythema as well as maximum and cumulative doses were higher with 20% escalations, whereas response rates and time to response did not significantly differ.Limitations
The study was limited by its retrospective nature.Conclusion
A 5% or 10% incremental regimen may have similar therapeutic efficacy.
