Effect of Body Mass Index on Intraoperative Complications During Hepatic Resection for Malignancy.
Article in ANZ journal of surgery. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled 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.
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
backgroundEvidence shows that high body mass index (BMI) contributes to increased postoperative complications in gastrointestinal surgery and suggests that it may contribute to intraoperative adverse events. We primarily aimed to determine if high BMI results in increased intraoperative adverse events in liver resections using the ClassIntra classification.
methodsA retrospective audit of liver resections under a single adult Hepatobiliary unit was performed from February 2018 to October 2023. We compared intraoperative adverse events and postoperative complications between BMI groups ('Normal/low' BMI < 25, 'Overweight' BMI 25-30 and Obese > 30). Resections were divided by complexity into minor, intermediate and major resections by extent of liver resection.
resultsOne hundred and ninety-nine patients were included in the analyses. Higher BMI was associated with a significantly greater proportion of intraoperative complications using the ClassIntra classification (p = 0.022). At least one intraoperative complication was sustained by 33.3% and 38.2% of overweight and obese patients, respectively, compared to 19.1% in normal/low weight individuals. There were no differences in other intraoperative or postoperative outcomes or complications with a higher BMI, including estimated blood loss, morbidity by Clavien-Dindo classification, 30-day readmission or mortality. Multivariate analysis showed that BMI class and diabetes status were significantly related to higher ClassIntra complication level (p = 0.0086).
conclusionHigher BMI is associated with increased rates of intraoperative adverse events during liver resection surgery, by measure of ClassIntra classification. Prospective standardised assessment of intraoperative complications is required to confirm these findings.
