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

backgroundAeromonas species are increasingly recognized as emerging human pathogens capable of causing a wide spectrum of infections ranging from skin and soft tissue infections to life-threatening bacteremia. Data from India describing their clinical spectrum and antimicrobial resistance patterns remain limited.

methodsWe conducted a retrospective study of 61 culture-proven cases of Aeromonas infection identified between 2019 and 2025 at a tertiary care centre in South India. Demographic characteristics, clinical presentation, comorbidities, microbiological findings, antimicrobial susceptibility patterns, treatment, and outcomes were analysed.

resultsThe mean patient age was 46 years, and 57% were male. The most common clinical presentations were skin and soft tissue infections (40.9%) and bacteremia (40.9%), while pulmonary and urinary infections were less frequent. Common comorbidities included diabetes mellitus (27.8%) and chronic liver disease (14.7%), and trauma preceded infection in 16.3% of cases. Antimicrobial susceptibility testing showed high resistance to carbapenems, with resistance rates of 54.7% to meropenem and 27.8% to imipenem. In contrast, cephalosporins largely retained activity. Overall, 81.9% of patients recovered, whereas the mortality rate was 13.1%

conclusionAeromonas infections present with diverse clinical manifestations and may show substantial resistance to carbapenems. Early microbiological diagnosis and rational antibiotic selection are essential for optimal management and improved outcomes.
