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
Background: Postoperative infection is a serious complication in older adults undergoing surgery for intertrochanteric femoral fracture (IFF). This study aimed to develop a simple scoring system and nomogram for predicting postoperative infection using routinely available preoperative indicators. Methods: A retrospective analysis was conducted on 286 older adult IFF patients (25 with postoperative infection, 261 without) treated at a single tertiary hospital. Optimal cut-off values were determined using the Youden index. Univariate and multivariate logistic regression identified independent risk factors. A nomogram and a simple scoring system (0-3 points) were constructed. Model performance was assessed by AUC, calibration curve, and subgroup analyses. Bootstrap resampling (500 iterations) was used for internal validation. Results: Multivariate analysis confirmed the CRP/albumin ratio (OR = 2582.84, 95% CI: 201.44-67,929.9, Conclusion: In this single-center retrospective cohort, the CRP/albumin ratio, fasting glucose, and surgery duration were independent predictors of postoperative infection in older adults with IFF. The proposed simple scoring system and nomogram provide practical tools for risk stratification; however, external validation in multicenter prospective cohorts is warranted before widespread clinical implementation.
