Waist-to-Height Ratio as a Predictor Complementary to BMI for Postoperative Pancreatic Fistula After Pancreatoduodenectomy for Periampullary Tumors.
Article in Annals of surgical oncology, 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
backgroundObesity is a known risk factor for postoperative pancreatic fistula (POPF) after pancreatoduodenectomy (PD). However, the body mass index (BMI) does not adequately reflect fat distribution or distinguish between fat and muscle mass. The waist-to-height ratio (WHR), an indicator of central adiposity, may provide complementary value to BMI in assessing the risk of POPF.
methodsThis study retrospectively analyzed 523 patients who underwent PD, excluding those with pancreatic cancer. Preoperative computed tomography (CT) was used to evaluate BMI, WHR, and visceral/subcutaneous fat area. The study defined POPF as International Study Group on Pancreatic Surgery (ISGPS) grade B or C. The distributions of BMI and WHR were examined, and the predictive performance of POPF was evaluated.
resultsThe overall incidence of POPF was 52.2%. Although only 16.8% of the patients met the BMI-based definition of obesity (BMI ≥ 25 kg/m
conclusionThe WHR is a simple and useful marker that complements BMI in preoperative assessment of the risk of POPF. It can identify patients with central adiposity who may not be classified as obese by BMI alone, thus enhancing preoperative risk stratification.
