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
In this study, we aimed to investigate the efficacy and safety of combined fractional carbon dioxide laser and topical timolol maleate 0.5% solution versus topical timolol maleate 0.5% solution alone in inflammatory acne. Thirty adult patients with inflammatory facial acne were randomized in this study. The patients received 3 biweekly sessions of fractional CO2 laser on one side of the face followed by topical timolol maleate ophthalmic solution 0.5% once daily for 7 days on both sides. Outcome was evaluated 2 weeks after the first session, 2 weeks after the last session, and 1 month after the last session by lesion count, erythema, hyperpigmentation, qualitative global scarring grading, and patients' satisfaction. Side effects were also evaluated. Trial registration (IRB No. 417, 30/10/2023). At 2 weeks after the first session, there were insignificant differences between both sides regarding lesion count, erythema, hyperpigmentation, and qualitative global scarring grading (p value = 0.8, 0.05, 0.7, 0.1 respectively). At 2 weeks after the last session, the erythema on the combined side was reduced by a mean of 0.2 ± 0.4 SD compared to timolol only side with significant difference between both sides (p value = 0.03), while there were insignificant differences between both sides regarding lesion count, hyperpigmentation, qualitative global scarring grading, and patients' satisfaction (p value = 0.1, 0.5, 0.8, 0.3 respectively). Recurrence was detected at one month after the last session. No side effects were reported. Combined fractional CO2 laser and topical timolol maleate 0.5% solution were significantly more effective than topical timolol maleate 0.5% solution alone in reduction of erythema of inflammatory facial acne in adolescent men with Fitzpatrick's skin type III-IV at 2 weeks after 3 biweekly sessions with insignificant differences between both sides regarding lesion count, hyperpigmentation, qualitative global scarring grading, and patients' satisfaction. Further and larger studies are still needed.
