The efficacy of red and blue light-emitting diode phototherapy combined with oral minocycline for acne conglobata: a retrospective cohort study.

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: Acne conglobata (AC) is a severe inflammatory skin condition with limited therapeutic options that can provide rapid and sustained remission. This retrospective cohort study aimed to evaluate the clinical efficacy and safety of a combination therapy of twice-weekly red-blue light-emitting diode (LED) phototherapy with a shortened 4-week course of oral minocycline, compared to a conventional polypharmacy regimen for AC. Methods: We analyzed clinical data from 28 outpatients diagnosed with AC. The study group ( Results: Baseline characteristics were comparable between groups. The LED-minocycline combination resulted in significantly superior and more rapid clinical improvement. At week 8, 100% of patients in the study group achieved cure (SSRI ≥90%), versus 0% in the control group ( Conclusion: Combining red-blue LED phototherapy with a 4-week course of minocycline is a rapid, highly effective, and safe therapeutic strategy for AC, outperforming conventional polypharmacy while halving the duration of systemic antibiotic exposure. Despite the inherent limitations of a retrospective design, these findings support the integration of LED therapy to optimize the management of severe acne.
