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
backgroundThis study aims to construct a nutrition-based nomogram for predicting the risk of intra-abdominal infection (IAI) after D2 radical gastrectomy for gastric cancer (GC).
methodsWe retrospectively analyzed the clinical data of 404 individuals who received D2 radical gastrectomy for GC. Four preoperative nutrition-related indicators, the nutritional risk screening (NRS) 2002 score, albumin (ALB), prognostic nutritional index (PNI), and controlling nutritional status (CONUT) score, were collected and calculated. Multivariate logistic regression analysis was utilized to screen the independent risk factors for IAI following D2 radical gastrectomy for GC. The area under the receiver operating characteristics (ROC) curve (AUROC) was computed. A nomogram was established to forecast postoperative IAI using the independent risk factors.
resultsThe NRS2002 score, ALB, PNI, CONUT score, fasting blood glucose (FBG), American Society of Anesthesiologists (ASA) score, type of resection, multi-visceral resection, perioperative blood transfusion, and the tumor, node, metastasis (TNM) stage were significantly associated with postoperative IAI. Considering the collinearity between these nutrition-related variables, four multivariate logistic regression analyses were separately performed, and four independent nutrition-based models were constructed. Of these, the best one was the model based on the three indicators of NRS2002 score, FBG, and multi-visceral resection, which had an AUROC of 0.744 (0.657-0.830), with a specificity of 75.6% and a sensitivity of 62.9%. Further, a nomogram was constructed to estimate the probability of IAI following D2 radical gastrectomy. The internal validation was carried out using the bootstrap method with self-help repeated sampling 1000 times, and the concordance index (c-index) was determined at 0.742 (95% CI = 0.739-0.745). The calibration curve revealed that the predictive results of the nomogram were in excellent concordance with the actual observations. The decision curve analysis (DCA) indicates that the nomogram has excellent clinical benefit.
conclusionThe nomogram constructed based on NRS2002 score, FBG, and multi-visceral resection has good predictive capacity for the incidence of IAI following D2 radical gastrectomy and provides a reference value for clinicians to assess the risk of IAI occurrence.
