Effect of hypoalbuminemia on postoperative pulmonary complications after thoracoscopic anatomical lung resection: a retrospective cohort study.
Article in PeerJ, 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
Objectives: Anatomical segmental resection is a standard treatment for non-small cell lung cancer but frequently entails postoperative pulmonary complications (PPCs). Serum albumin level, as useful assessment of changes in nutritional status, is closely associated with postoperative outcomes. Therefore, we evaluated the impact of preoperative albuminemia level on PPCs in thoracoscopic anatomical lung resection. Methods: We conducted a retrospective analysis of clinical data from 1,192 patients who underwent elective thoracoscopic anatomical lung resection owing to pulmonary tumors or other diseases at the First Affiliated Hospital of Nanjing Medical University between January 2020 and December 2020. Patients were stratified into a hypoalbuminemia group (<35 g/L) and a normal albumin group (≥35 g/L) based on the lowest albumin concentration in the 48 h before operation. Demographics, perioperative data, and PPCs incidence were compared between groups. Propensity score matching (PSM) was employed to balance baseline characteristics, after which PPCs incidence was recompared. Multivariate regression was performed to assess excess risks for PPCs associated with hypoalbuminemia, adjusted for demographics and clinical variables. Results: Among the 1,192 patients included, the overall incidence rate of PPCs was 26.7% (319/1,192), with pneumonia being the most common complication (16.0%). Preoperative hypoalbuminemia was present in 224 patients (18.8%). After PSM, the hypoalbuminemia group had a significantly higher incidence of PPCs compared to the normal albumin group ( Conclusion: Preoperative hypoalbuminemia is an independent predictor of PPCs, particularly pneumonia, in patients with normal pulmonary function undergoing thoracoscopic anatomical lung resection.
