Global trends in the proportion of macrolide-resistant Mycobacterium Species: A systematic review and meta-analysis.
Synthesis in PloS one, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundMacrolide resistance in Mycobacterium species is an emerging global problem, complicating treating non-tuberculous mycobacteria (NTM) and Mycobacterium tuberculosis. Understanding global resistance patterns is essential to improve treatment strategies and reduce morbidity and mortality.
objectiveThis study aimed to investigate macrolide resistance prevalence, distribution, and trends among Mycobacterium species in different world regions.
methodsA comprehensive search of Scopus, PubMed, Web of Science, and EMBASE (2015-2023) assessed study quality using JBI guidelines. Resistance proportions were calculated with a random-effects model, and additional meta-regression and subgroup analyses explored variations and trends. Statistical analyses were conducted using R and the metafor package.
resultsOut of 5,718 records, 41 studies across 17 countries were included. Azithromycin resistance was reported in 17 reports (3 Studies), with 156 resistant isolates among 715 tested, yielding a pooled rate of 29.0% (95% CI: 19.5-40.7%). Clarithromycin resistance, assessed in 76 reports (40 Studies), included 1,071 resistant isolates among 3,923 tested, with a pooled rate of 30.5% (95% CI: 23.7-38.2%). Erythromycin resistance was reported in 17 reports (3 Studies), with 350 resistant isolates among 752 tested, giving a pooled rate of 50.3% (95% CI: 37.5-62.9%). Meta-regression revealed a significant upward trend in azithromycin resistance over time (r = 0.558, p = 0.005).
conclusionThese findings underscore the need for targeted, region- and species-specific interventions to combat rising macrolide resistance in Mycobacterium species effectively.
