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
Objective: To construct a nomogram prediction model for ileus after radical gastrectomy for gastric cancer. Methods: The 424 gastric cancer patients were assigned into a modeling group of 297 cases and a validation group of 127 cases. The modeling group was assigned into the ileus group of 54 cases and the non ileus group of 243 cases based on the occurrence of postoperative ileus. LASSO regression analysis and multivariate logistic regression analysis were used to screen the influencing factors of ileus after radical gastrectomy for gastric cancer. The nomogram model was constructed for predicting ileus after radical gastrectomy for gastric cancer. The calibration curve was used to evaluate the calibration degree of the model. ROC curve was used to evaluate the model discrimination. The clinical decision curve was used to analyze the clinical applicability of the model. Results: LASSO regression analysis and multivariate logistic regression analysis showed that age (OR=4.999), previous abdominal surgery (OR=3.836), operative time (OR=3.541), IL-6 (OR=1.339), and TNF-α (OR=8.254) were all independent risk factors for ileus after radical gastrectomy for gastric cancer (P<0.05). The deviation correction curves of the modeling group and the validation group were both close to the ideal curve, with Hosmer-Lemeshow test showed x Conclusion: The nomogram prediction model constructed in this study can serve as an early warning indicator for ileus after radical gastrectomy for gastric cancer, guiding clinical decision-making.
