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 aimed to develop and validate a PET/CT radiomics combined model integrated with visualization tools for preoperative risk stratification of high-grade invasive lung adenocarcinoma (ILA).
methodsA total of 202 ILA patients with 207 pathologically confirmed lesions were retrospectively enrolled and randomly divided into training (70%) and validation (30%) sets. Patients with ≥ 20% micropapillary or solid subtypes were classified as the high-risk group. Multivariate logistic regression was used to develop combined clinical and radiomics models. Model performance was evaluated using ROC, calibration, and decision curve analyses, and visualized with Shapley Additive exPlanations (SHAP) and a nomogram.
resultsThe combined model demonstrated superior diagnostic performance, with higher AUCs (Delong test, all P < 0.05) and calibration curves (Hosmer-Lemeshow test, all P > 0.05), outperforming the clinical model in both the training and validation datasets. It also provided greater clinical net benefit across the central decision threshold range of 0.15 to 0.85. SHAP analysis identified Radscore and SUVmax (mean SHAP values = 0.35 and 0.2, respectively) as the primary risk factors for high-grade ILA.
conclusionWe validated a PET/CT-based combined model utilizing SHAP analysis and a nomogram for preoperative risk stratification in high-grade ILA. The model exhibits high accuracy, commendable calibration, and clinical benefit. This noninvasive, interpretable instrument facilitates objective risk assessment, personalized decision-making, and precise management for ILA.
