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
Objective: This study aimed to investigate the effectiveness of photodynamic therapy combined with 2% salicylic acid for treating moderate acne. Methods: This retrospective study included outpatients with moderate acne who consulted the Department of Dermatology at Suining First People's Hospital in Sichuan Province between April 2019 and December 2019. The patients were grouped into the photodynamic group, the salicylic acid group, and the combination therapy group, according to whether they received aminolevulinic acid photodynamic therapy, a 2% supramolecular salicylic acid topical masque applied once daily for 10 minutes and then washed off for four consecutive weeks, 2% salicylic acid therapy, or both treatments combined. The overall effective rate was calculated as the percentage of patients with a 60% or greater reduction in skin lesions. Adverse reactions were also collected. Results: A total of 66 patients were included, with 22 patients in each group. The combination therapy group had an overall effective rate of 72.73%, which was higher compared to the photodynamic group at 40.91% and the salicylic acid group at 22.73% (5 cases, Conclusion: Photodynamic therapy combined with 2% salicylic acid therapy reduced the number of skin lesions in patients with moderate acne more than either treatment alone. The combination therapy may be tolerable with no severe adverse reactions.
