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
objectiveTo investigate the feasibility and clinical efficacy of bilateral crossover decompression technique under percutaneous spinal endoscopic surgery for thoracic ossification of the posterior longitudinal ligament (T-OPLL).
methodsA retrospective analysis was conducted on 18 patients with T-OPLL who underwent bilateral crossover percutaneous spinal endoscopic surgery between January 2020 and December 2023. There were 10 males and 8 females, with a mean age of 54.8 years. Surgical levels included T
resultsThe mean total operative time was 102.39 min (range: 90-130 min), intraoperative blood loss was 40.61 ml (range: 30-55 ml), and mean hospital stay was 10.22 days (range: 8-14 days). All patients were followed up for a mean duration of 16.78 months (range: 12-24 months). Compared with the preoperative period, mJOA scores significantly improved at 3 days, 6 months, and at the final follow-up (p < 0.05), with further improvement observed at the final follow-up compared with 3 days and 6 months postoperatively (p < 0.05). Similarly, ODI scores were significantly reduced at 3 days, 6 months, and at the final follow-up compared with preoperative scores (p < 0.05). According to the modified MacNab criteria at the final follow-up, 9 cases were rated as excellent, 7 as good, and 2 as fair, yielding an excellent-to-good rate of 88.89%. Compared with preoperative measurements, both the sagittal canal diameter and canal area were significantly increased at 3 days, 6 months, and at the final follow-up (p < 0.05). Complications included intercostal neuralgia in 2 patients, dural tear in 2 patients, and transient postoperative muscle weakness in 1 patient; no cases of epidural hematoma, neck pain, or iatrogenic neurological injury were observed.
conclusionBilateral crossover decompression percutaneous spinal endoscopic surgery is a safe and effective minimally invasive technique for the treatment of T-OPLL, with satisfactory short-term clinical outcomes.
