1 · What the graph read from it

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.

2 · The registry

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

aimsSulfamethoxazole-trimethoprim (SMX-TMP) is a widely used antibiotic for treating bacterial infections, but its safety in adult outpatients remains understudied. This systematic review and meta-analysis evaluated the safety profile of SMX-TMP and identified critical research gaps. The pharmacovigilance study aimed to validate and extend findings from meta-analyses to better understand the real-world safety of SMX-TMP.

methodsWe searched MEDLINE and Embase up to 12 August 2024, to identify studies comparing adverse drug events (ADEs) following SMX-TMP vs. other antibiotics in adult outpatients. Meta-analyses were performed where data allowed. A pharmacovigilance study using the Food and Drug Administration Adverse Event Reporting System was conducted to supplement our findings.

resultsOur review, which included 43 studies, found SMX-TMP had a nearly 3-fold higher risk of rash compared to other antibiotics (pooled risk ratio 2.56, 95% confidence interval [1.69, 3.89], I

conclusionOur meta-analyses and pharmacovigilance study suggested SMX-TMP was associated with increased risk of ADEs compared to other antibiotics including amoxicillin/clavulanate, azithromycin and nitrofurantoin. Further robust research is essential to confirm these safety signals and guide clinical practice.
