title: In search of an optimum dose escalation for narrowband UVB phototherapy: is it time to quit 20% increments?
abstract: OBJECTIVE
  Our aim was to compare 20% with 10% to 5% incremental regimens in narrowband UVB phototherapy.
  
  
  METHODS
  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.
  
  
  CONCLUSIONS
  The study was limited by its retrospective nature.
  
  
  CONCLUSIONS
  A 5% or 10% incremental regimen may have similar therapeutic efficacy.
