Modalities of follow-up after surgical plication for diaphragmatic paralysis.
Article in Journal of thoracic disease, 2025. 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
Background: Treatment of symptomatic diaphragmatic paralysis by surgical diaphragm plication provides relief to many patients, but there are no guidelines for follow-up. The aim of our study is to evaluate long-term results of diaphragm plication and to outline follow-up modalities. Methods: We conducted a retrospective monocentric study including all the patients with unilateral diaphragmatic paralysis (UDP) consecutively operated between January 2006 and December 2021. Benefits of surgery were evaluated on dyspnea, spirometry and repeated measurements of the distance from apex to diaphragm (A-D) on chest X-ray. Results: A total of 23 patients were included; 60% were women. Etiology of diaphragmatic eventration was idiopathic in 14 patients (61%), iatrogenic in 3 patients (13%) and post-traumatic in 6 patients (26%). All patients had dyspnea at diagnosis with a significant reduction of vital capacity (VC) from seated to supine position, decreasing from 71.2%±18.7% to 59%±26.5% (P=0.002). All patients were operated by thoracotomy with an average hospital stay of 7.7±5 days. No postoperative mortality was observed. Median follow-up was 19 months. There was a statistically significant (P=0.001) improvement in the Medical Research Council (MRC) dyspnea score at 6 months persistent at last follow-up. VC improved from 71.2%±18.7% to 88.1%±19.4% at last follow-up (P=0.03). Chest X-ray showed a significant increase in the A-D distance from 12±3.2 to 19±2.8 cm at 6 months (P=0.001) and 17.9±3.59 cm at remote (P=0.001). A significant correlation was found between A-D distance and dyspnea, but not between X-ray measurements and VC. Conclusions: Diaphragm plication effectively alleviates dyspnea in patients with diaphragmatic paralysis. Good functional results are persistent at 2 years. The correlation between chest X-ray and dyspnea suggests that these parameters may suffice for follow-up.
