Correlation of residual lung complications with radiological findings after pulmonary segmentectomy.
Article in Surgery today, 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
purposeTo investigate the clinical characteristics of residual lung complications following segmentectomy.
methodsAmong 901 patients who underwent segmentectomy for lung cancer between 2009 and 2022, 256 patients who underwent postoperative computed tomography (CT) for abnormal shadows on chest radiography were retrospectively evaluated and categorized into three groups: Type 1 (consolidation only adjacent to the intersegmental line), Type 2 (partial infiltration extended to the residual segment [< 50%]), and Type 3 (infiltration extended to the large area of the residual segment [≥ 50%]). The association between the CT findings and complications was also assessed.
resultsThere were no significant differences in the background factors among the three types. However, Type 3 patients experienced more severe pulmonary-related complications than Types 1 and 2 (45.8% vs. 25.0%, P = 0.002). Most patients (n = 894, 99.2%) were discharged without surgical intervention, but seven (0.78%) required reoperation for complications. Of these, six had Type 3 CT findings, and five underwent left upper division segmentectomy.
conclusionsExtensive postoperative infiltrative shadows in the residual segment are associated with severe complications after segmentectomy. In cases in which the shadow occupies more than half of the remaining segment, special attention to postoperative management is necessary to prevent lethal complications.
