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
backgroundPostoperative pulmonary infection (PPI) remains a significant complication in elderly patients with colorectal cancer (CRC). This study aimed to identify risk factors for PPI and develop a predictive model for PPI.
methodsA retrospective analysis was conducted on 339 elderly patients with CRC undergoing radical resection. Patients were categorized into PPI and non-PPI groups. Clinical, surgical, and laboratory variables were collected. Univariate and multivariate logistic regression analyses were performed, and independent predictors of PPI were identified. A nomogram was constructed and validated internally by R.
resultsIn a study of 339 patients, 40 individuals developed PPI with an incidence of 11.8%. The study identified five independent risk factors: advanced age (OR = 1.13, 95%CI: 1.03-1.25, P = 0.014), increased mFI positive items (OR = 3.19, 95%CI: 1.70-5.99, P < 0.001), elevated CONUT (OR = 2.23, 95%CI: 1.25-3.98, P = 0.007), decreased GNRI (OR = 0.94, 95%CI: 0.90-0.99, P = 0.010) and PNI scores (OR = 0.88, 95%CI: 0.81-0.97, P = 0.010). The nomogram displayed good discrimination (AUC: 0.82) and calibration. Independent validation from the same institution confirmed excellent performance (AUC: 0.866).
conclusionsAge, mFI, and poor nutritional status are independent predictors of PPI in elderly patients with CRC. This nomogram serves as a practical tool for individualized risk assessment and perioperative management.
