Early precise screening of pulmonary nodules: risk factor analysis for malignant nodules.
Article in American journal of translational research, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
objectivesTo analyze clinical data and CT imaging characteristics of patients with pulmonary nodules, clarifying the diagnostic value of CT features in distinguishing benign from malignant pulmonary nodules. To enhance diagnostic accuracy for pulmonary nodule characterization, assisting clinicians in diagnosis and providing optimal treatment recommendations.
methodsThis retrospective study included 200 individuals who underwent dual-source CT lung cancer screening at the First Affiliated Hospital of Air Force Military Medical University from January 2023 to December 2023. Participants were categorized into benign and malignant groups based on pathological reports, with 102 cases in the benign group and 98 in the malignant group. Postoperative pathological outcomes were documented, and risk factors for lung cancer were analyzed, stratifying results by pathology and infiltration level.
resultsPatients in the malignant group had significantly higher NICAp and CTAp values than those in the benign group (all P < 0.05). The diagnostic accuracy of chest CT for identifying benign vs. malignant nodules was 88.78%, with a sensitivity of 44.90% and a specificity of 57.84%. CT examination positivity was 42.16% in the benign group and 44.90% in the malignant group. Univariate and multivariate analyses identified NICAp (95% CI 1.045-1.367; P = 0.007), CTAp (95% CI 1.341-4.123; P = 0.005), solid nodule (95% CI 1.198-2.978; P = 0.008), and nodule density (95% CI 1.128-2.987; P = 0.007) as independent diagnostic factors for malignant nodules.
conclusionNICAp, CTAp, solid nodule, and nodule density are independent diagnostic factors for malignant pulmonary nodules.
