Post-pneumonectomy-like syndrome as a result of unilateral upper-lung field pulmonary fibrosis after lung cancer surgery: a case report.
Article in Respiratory medicine case reports, 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
Post-pneumonectomy syndrome is a rare complication following pneumonectomy, characterized as significant mediastinal shift and rotation toward the operated side, resulting in stenosis of trachea and bronchi. We report the case of a 60-year-old woman who underwent right lower lobectomy for lung adenocarcinoma in 2017. She subsequently developed unilateral upper-lung field pulmonary fibrosis (upper-PF) in the operated side, radiologically consistent with pleuroparenchymal fibroelastosis, as a late surgical complication. By 2025, the resulting mediastinal right shift due to upper-PF caused the descending aorta to severely compress the left main bronchus, leading to acute hypercapnic respiratory failure. While typically recognized as post-pneumonectomy syndrome, this condition is extremely rare following lobectomy. This case demonstrates that unilateral upper-PF development can induce a post-pneumonectomy-like syndrome, even in patients who have not undergone a pneumonectomy.
