Effectiveness of narrowband UVB phototherapy and psoralen plus UVA photochemotherapy in the treatment of generalized lichen planus: Results from a large retrospective analysis and an update of the literature.
Article in Photodermatology, photoimmunology & photomedicine, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers, 1 of them a synthesis that pooled it.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThe aim of this retrospective study was to compare the efficacy and safety of different phototherapeutic modalities in the treatment of cutaneous lichen planus (LP).
methodsWe retrospectively analyzed the chart data of 53 patients with generalized LP who had been subjected to narrowband UVB (NB-UVB) or photochemotherapy (PUVA) between January 1997 and April 2020. Of these, 30 patients had received NB-UVB, 18 patients oral PUVA and 5 patients bath PUVA.
resultsFifty patients completed a full treatment course. The percentage of patients with a complete (>90% clearing) or good (51%-90% clearing) response was similar for NB-UVB versus PUVA (86.2% vs. 90.5%; P = 1.00). The number of exposures required for obtaining a complete or good response was also comparable for both treatment groups (NB-UVB: 28.9 ± 12.3 vs. PUVA: 25.4 ± 10.1; P = .209). Adverse events, in particular gastrointestinal upsets, were recorded in 26.1% of patients treated with oral PUVA while none were observed with NB-UVB.
conclusionThe therapeutic outcome and the number of treatments required for achieving a complete or good response were comparable for NB-UVB and PUVA; however, PUVA therapy was associated with a substantially higher rate of moderate adverse events.
