Three-dimensional reconstruction for determining positional indications of pulmonary segmentectomy/subsegmentectomy for ground glass opacity-dominant clinical T1a-bN0 non-small cell lung cancer.
Article in Translational lung cancer research, 2024. 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
Background: The precision of segmentectomy/subsegmentectomy for ground glass opacity (GGO)-dominant cT1a-bN0 non-small cell lung cancer (NSCLC), including mono-segmentectomy, mono-subsegmentectomy, combined subsegmentectomies, and single segmentectomy with adjacent subsegmentectomy, has improved. The aim of this study is to investigate their positional indications by focusing on the three-dimensional location of lesions, utilizing three-dimensional computed tomography bronchography and angiography (3D-CTBA). Methods: We retrospectively analyzed 195 patients with GGO-dominant cT1a-bN0 NSCLC who underwent segmentectomy/subsegmentectomy between August 2015 and November 2020. We included 173 patients: mono-segmentectomy (71, 41.04%), mono-subsegmentectomy (37, 21.39%), combined subsegmentectomies (42, 24.28%), and single segmentectomy with adjacent subsegmentectomy (23,13.29%). Patient demographics and perioperative outcomes were compared among groups to identify positional indications. Results: Significant differences were observed among the four groups in terms of lobe location of the lesions and their relationships with adjacent intersegmental veins (P<0.001), but not in their diameter and depth (P=0.33; P=0.79). All groups showed similar surgical margins (P=0.77) despite differences in the number of subsegments resected (P<0.001). No perioperative deaths or postoperative recurrences were reported. For lesions located in the middle region, located inter-segmentally, or with a diameter >1 cm, a greater number of subsegments were resected (P=0.02; P<0.001; P=0.003), while the surgical margins were not inferior to those located in the outer region, located intra-segmentally, or with a diameter ≤1 cm (P=0.29; P=0.77; P=0.46). Conclusions: It is the specific lobe in which lesions are located and their relationship with adjacent intersegmental veins that determine the specific surgical procedure of segmentectomy/subsegmentectomy for GGO-dominant cT1a-bN0 NSCLC, rather than their diameter and depth.
