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: Various preventive measures and treatment methods exist to prevent paraplegia during thoracic aortic surgery. Postoperative cerebrospinal fluid drainage (CSFD) is one of the treatment options when paraplegia occurs. This study aimed to evaluate the neurological efficacy of postoperative CSFD in patients undergoing thoracic aortic and thoracoabdominal aortic surgery. Methods: We analyzed perioperative data from 85 patients who underwent perioperative CSFD for thoracic and thoracoabdominal aortic surgery between January 2006 and December 2022, focusing on neurological changes. A total of 61 patients (72%) received preoperative CSFD, and 24 patients (28%) received postoperative CSFD. Perioperative neurological data were analyzed with a focus on perioperative changes. Results: In the postoperative CSFD group, the manual muscle test (MMT) score before CSFD was 0.8, that just after CSFD was 2.4, and that at discharge was 3.0. Therefore, postoperative CSFD improved MMT scores compared with preoperative CSFD. The mean time between surgery completion and postoperative CSFD implantation was 9.8 hours. However, 6 (25%) of the patients who developed postoperative paraplegia and underwent early postoperative CSFD remained paraplegic without any improvement. In the preoperative CSFD group, there was only one case (2%) of postoperative paraplegia. Conclusions: Postoperative CSFD improved the neurological prognosis of individuals undergoing thoracic aortic and thoracoabdominal aortic surgery. However, 25% of the patients remained paraplegic despite postoperative CSFD.
