Prediction of Histological Subtype Based on Segmental Localization of Malignant Pulmonary Nodule in the Upper Lobe of the Lung.
Article in Thoracic cancer, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundStudies have shown that malignant pulmonary nodules frequently occur in the upper lobes of the lung. However, there is no data on their distribution according to segments. The aim of this study is to predict the histological subtype of lung cancer based on the segment localization of malignant pulmonary nodules located in the upper lobe of the lung.
methodsBetween March 1, 2018, and November 1, 2024, 2402 patients who applied to the pulmonary diseases outpatient clinic and were scheduled for further investigation after thoracic CT scans revealed pulmonary nodules measuring 8 mm or larger were screened. The demographic characteristics, pulmonary nodule size, and histological subtypes of 154 patients diagnosed with non-small cell lung cancer (NSCLC) in further investigations were compared according to the upper lobe segments of the lung: apicoposterior and anterior.
resultsAdenocarcinoma percentage was significantly higher in the apicoposterior group, while squamous cell carcinoma percentage was significantly higher in the anterior group (p = 0.010).
conclusionsNSCLC localized in the apicoposterior segment of the upper lobes of the lung tends to be adenocarcinoma, while those localized in the anterior segment tend to be squamous cell carcinoma. Tumor size less than 3 cm with apicoposterior localization is independently associated with the adenocarcinoma histological subtype.
