Outcomes of alternative therapy in HLA-B* 13:01 positive leprosy patients without dapsone versus standard MDT in negative patients: A comparative effectiveness 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
backgroundIn HLA-B*13:01-positive multibacillary (MB) leprosy patients, dapsone-containing multidrug therapy (MDT) carries a high risk of dapsone hypersensitivity syndrome (DHS). Alternative regimens (dapsone-free) are adopted, but their long-term efficacy compared with standard MDT in HLA-B*13:01-negative patients remains inadequately characterized. METHODOLOGY: This retrospective cohort study analyzed MB patients (2015-2023) from the National Leprosy Prevention and Control Management Information System (LEPMIS) with ≥1-year follow-up. Primary outcomes (cure/relapse rates, bacterial index (BI), leprosy reactions, and disability progression) and secondary outcomes (adverse events and treatment duration) were compared between HLA-B*13:01-positive patients receiving alternative therapy (rifampicin + clofazimine ± clarithromycin/ofloxacin/minocycline) and negative patients receiving standard MDT (rifampicin + clofazimine + dapsone).
findingsAmong the 271 enrolled MB patients (120 HLA-B*13:01-positive, 151 negative), alternative therapy showed comparable efficacy to standard MDT in cure rates (67.6% vs. 65.8% at Year 5), the rate of BI decline (89.92% vs. 95.11% at Year 5), smear negativity rates (71.43% vs. 75.00% at Year 5) and relapse rates (0.46 vs. 0.20 per 100 person-years). Kaplan-Meier survival functions revealed no significant differences in leprosy reactions or disability progression. Additionally, alternative therapy demonstrated comparable safety to MDT (1.67% vs. 2.65%, P = 0.70).
conclusionsIn our study, dapsone-free alternative regimens demonstrated comparable clinical efficacy and safety to standard MDT in MB patients, providing a viable option for HLA-B*13:01 carriers. These findings, limited by the observational design and regimen heterogeneity, warrant further investigation in prospective trials.
