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
purposeOccasionally, lobes displace after lobectomy, which is referred to as "lobar shifting". This study aimed to evaluate the effect of lobar shifting on postoperative pulmonary function.
methodsWe analyzed the records of 761 patients who underwent lobectomy between 2012 and 2022. The patients were categorized based on three-dimensional computed tomography (3D-CT) images into those with (shift group: n = 510) and those without (non-shift group: n = 251) their postoperative subject bronchus shifting toward the head or dorsal side. The preservation rate of forced expiratory volume in one second (FEV1.0) was compared between the two groups. Several factors were investigated to identify the cause of lobar shifting.
resultsFEV1.0 preservation rates, excluding left upper lobectomy, were significantly better in the shift group than in the non-shift group (all patients: 87.9% vs. 84.9%, p < 0.001; right upper lobectomy: 90.1% vs. 85.4%, p = 0.002; right lower lobectomy: 90.0% vs. 84.5%, p = 0.002; left upper lobectomy: 82.0% vs. 83.9%, p = 0.43; left lower lobectomy: 90.0% vs. 85.2%, p = 0.01). Factors that correlated with lobar shifting included age (p < 0.001), adhesions (p < 0.001), and lobulation (p = 0.001).
conclusionsLobar shifting may benefit postoperative pulmonary function, excluding after left upper lobectomy. Morphological factors contribute to lobar shifting.
