Preoperative visceral fat area predicts intraoperative adverse events during lymphadenectomy in laparoscopic gastrectomy for gastric cancer: a post hoc analysis.
Trial report in Surgical endoscopy, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to 2 registered trials, which are not on this map. Cited by 5 papers.
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.

Abstract
backgroundVisceral obesity has been increasingly recognized as a potential risk factor for surgical complications in gastric cancer surgery, yet its impact on lymphadenectomy during laparoscopic gastrectomy remains undefined. This study aimed to investigate the influence of visceral fat area (VFA) on intraoperative adverse events (iAEs) during lymphadenectomy in laparoscopic gastrectomy.
methodsA post hoc analysis was performed using data from two previous prospective studies ([NCT02327481] and [NCT01609309]). The patients were divided into high and low VFA groups based on preoperative computed tomography images at the umbilical level. All iAEs were reviewed from the surgical videos and graded using ClassIntra. The factors influencing iAEs were identified, and predictive models for iAEs were constructed.
resultsThis study included 490 patients, with 244 and 246 patients in the high and low VFA groups, respectively. Restricted cubic splines demonstrated a positive linear association between VFA and iAEs. Compared with the low VFA group, the high VFA group exhibited a significantly higher incidence of iAEs (29% vs. 12%, p < 0.001), primarily in the infrapyloric (9.0% vs. 2.0%) and suprapancreatic (23.4% vs. 9.3%) regions and higher rates of ClassIntra I-III. Multivariate logistic regression identified high VFA as an independent risk factor for iAEs (hazard ratio [HR] 2.16, 95% confidence interval [CI]: 1.22 - 3.83). Based on the VFA, nomograms were developed to predict iAEs (training area under the curve [AUC] 0.722, validation AUC 0.730). Meanwhile, a web-based calculator was developed to facilitate clinical application.
conclusionsHigh preoperative VFA is independently correlated with iAEs after laparoscopic gastrectomy for gastric cancer. Nomograms based on VFA showed potential in predicting iAEs, helping identify high-risk patients early and facilitating tailored perioperative management.
