Ungraded means an effect was reported without a GRADE rating; it is not a gap. No studies means the review found nothing to answer the question. The six categories are a display order, not a score.

Review question

ElementPlanned (methods)Found (results)
PopulationPeople with symptomatic, biopsy-confirmed OLP; not concurrently receiving other OLP treatment35 RCTs, 1474 participants (20 to 139 per study); 7 at low, 10-11 at unclear and 17-18 at high risk of bias
InterventionAny local or systemic corticosteroid treatmentTopical corticosteroids (n=32); systemic corticosteroids (n=2); intralesional corticosteroids (n=2)
ComparisonPlacebo; calcineurin inhibitor; another corticosteroid; any other local or systemic treatment; the same corticosteroid plus an adjunctive treatmentPlacebo (n=3); calcineurin inhibitors (n=11); other corticosteroids (n=8); other treatments (n=9); adjunctive treatments (n=6)
OutcomesPrimary: pain (score and resolution) assessed by participants at end of treatment. Secondary: clinical response (score and resolution); adverse effectsPain (score; resolution); clinical (score; resolution); adverse effects
Study designsRandomised controlled trials (RCTs) onlyRCT (n=35)
TimingMeasured at the end of the treatment course (between one week and six months)Treatment courses one week to six months (majority one to two months)
