Two-step photodynamic therapy for facial acne: a randomized controlled trial of pain reduction with 630 nm red light laser.
Trial report in Lasers in medical science, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Although topical 5-aminolevulinic acid photodynamic therapy (5-ALA PDT) is an effective treatment for facial acne, many patients report significant pain during the irradiation phase, compromising adherence. Two-step PDT, which modifies irradiance in two phases, has been proposed to reduce pain without compromising treatment efficacy. In this single-center, assessor-blinded randomized trial, 26 patients with facial acne were allocated to either a two-step PDT group (n = 12) or a conventional PDT group (n = 14). After applying 20% 5-ALA for 2 h, both groups received red light (630 ± 5 nm) to deliver a total fluence of 120 J/cm
