A nomogram to predict invasiveness in lung adenocarcinoma presenting as ground glass nodule.
Article in Translational cancer research, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
backgroundAdenocarcinoma in situ, minimally invasive adenocarcinoma, and invasive adenocarcinoma (IA) can all appear as a ground glass opacity (GGO) on chest computed tomography (CT). However, their respective prognoses are considerably different. This study aimed to predict IA in radiological examinations of patients with GGO lesions.
methodsWe retrieved the clinical records and high-resolution CT (HRCT) images of 124 patients with GGO lesions, who underwent various lung resections between 2016 and 2017. Correlations between the imaging features of preoperative HRCT and the postoperative pathology were analyzed. Receiver-operating characteristic (ROC) curve analysis, chi-square test, and one-way analysis of variance and multiple logistic regression were performed. A nomogram was developed and analyzed using a multiple logistic model.
resultsThe maximum sensitivity and specificity were obtained at a cutoff value of -410 Hounsfield units (HU) for the mean CT value (m-CT), 10 mm for the maximum tumor dimension (MTD), and 0.25 for the consolidation tumor ratio (CTR). Further, there were significant differences in MTD, CTR, margin characteristics, air bronchogram, pleural indentation, and multiple GGOs (P<0.05). The independent predictive factors of IA included MTD [risk ratio (RR), 5.047; P=0.018], air bronchogram or vacuole sign (RR, 4.054; P=0.025), pleural retraction (RR, 4.742; P=0.008), and m-CT value (RR, 5.874; P =0.005). The scoring nomogram model was as follows: -3.50744 + 1.26374 × (MTD>10 mm=1) + 2.41978 × (m-CT value≥-410 HU=1) + 1.77779 × (with air bronchogram or vacuole sign=1) + 1.60913 × (with pleural retraction=1). The area under the ROC curve was 0.9. The cutoff score was -0.5502 with a sensitivity of 86.8% and a specificity of 78.9%.
conclusionsIA in patients with GGO lesions can be predicted by evaluating the MTD, m-CT value, air bronchogram, and pleural retraction on HRCT by using a nomogram model.
