Preoperative percent body fat in bioelectrical impedance analysis predicts pancreatic fistula after pancreaticoduodenectomy.
Observational study in Langenbeck's archives of surgery, 2023. 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
backgroundIt is unclear which body composition affects postoperative pancreatic fistula (POPF) after pancreaticoduodenectomy. In the present study, we evaluated the relationship between nutritional factors, body composition, and POPF.
methodsThis was a prospective observational cohort study. Patients who underwent pancreaticoduodenectomy between March 2018 and July 2021 were included in this study. Preoperative body composition was measured using a bioelectrical impedance analyzer. In addition, the predictive factors for POPF were analyzed using logistic regression model.
resultsThe study included 143 patients. Among these patients, 31 had POPF (POPF group) and 112 did not (non-POPF group) after pancreaticoduodenectomy. For body composition, the percent body fat was significantly higher in the POPF group (26.90 vs 23.48, P = 0.022). Multivariate analysis revealed that alcohol consumption (odds ratio 2.95, P = 0.03), pancreatic duct < 3 mm (odds ratio 3.89, P < 0.01), and percent body fat (odds ratio 1.08, P = 0.01) were significantly independent predictive factors for POPF. When the patients were divided into three groups based on their percent body fat (< 25, 25-35, and ≥ 35), POPF occurred more frequently in the group with ≥ 35 percent body fat (47.1%) than in the < 25 group (15.5%) (P = 0.008).
conclusionPredictive factors for POPF related to nutritional status, such as percent body fat, should be considered before proceeding to pancreaticoduodenectomy (ClinicalTrials.gov trial registration no. NCT5257434).
