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

purposeThe Tokyo Guidelines of 2018 recommend performing an intraoperative bile culture for acute cholecystitis. However, their clinical significance remains unclear. We evaluated the impact of performing a bile culture on the perioperative outcomes.

methodsWe retrospectively analyzed 344 patients who underwent cholecystectomy for acute cholecystitis between 2015 and 2024. The patients were classified into a culture group (n = 248) and a non-culture group (n = 96). The inverse probability of treatment weighting was applied to adjust for baseline differences. The perioperative outcomes were compared and the influence of performing a bile culture on antibiotic management was assessed.

resultsThe culture group had more Grade II/III tumors (p < 0.05). After adjustment, drain placement was more frequent (73.2% vs. 58.9%; p = 0.01). No significant differences were observed in the operative time (100 vs. 87 min, p = 0.10), gallbladder perforation (32.9% vs. 30.0%, p = 0.85), hospital stay (5 vs. 4 days, p = 0.30), or complications (24.0% vs. 18.0%, p = 0.273). In the culture group, 71.8% of the patients completed antibiotics before the culture results. Therapy was changed in only 2.0% of the patients.

conclusionsAlthough a bile culture is often performed in severe cases, it rarely influences the antibiotic strategy or improves the outcomes. Therefore, performing a routine intraoperative bile culture, as recommended by the Tokyo Guidelines 2018, may have limited utility.
