Prevalence of methicillin-resistant Staphylococcus aureus (MRSA) in street-vended tomato sauces in Dhaka, Bangladesh.
Article in BMC research notes, 2026. 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
objectiveTo assess the prevalence of Staphylococcus aureus and antimicrobial resistance patterns, with particular emphasis on methicillin resistance, among isolates from street-vended tomato sauces in Dhaka, Bangladesh.
resultsAmong 104 street-vended tomato sauce samples, 83 (79.8%; 95% Cl: 71.1-86.4%) were S. aureus isolates confirmed. Of these, 38 (45.8%) identified as methicillin-resistant Staphylococcus aureus, 5 (6.0%) vancomycin-resistant S. aureus, 55 (66.3%) multidrug resistance, and 2 (2.4%) extensively drug-resistant. The multiple antibiotic resistance (MAR) index ranged from 0.08 to 0.75 (mean ± SD = 0.38 ± 0.12), with 60 (72.3%) isolates exceeding the high-risk threshold (≥ 0.2). Methicillin-Resistant isolates showed significantly higher index values than susceptible isolates (p = 0.003). Co-resistance observed between oxacillin-cefoxitin (φ = 1.00) and meropenem-amikacin (φ = 0.96). Elevated resistance index values were more frequently observed among isolates from slum and transport-hub areas.
