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
Objective: To investigate the effect of the opening side selection in unilateral open-door laminoplasty (UODL) on postoperative outcomes for patients with cervical ossification of the posterior longitudinal ligament (OPLL) presenting with symptom-ossification mismatch. Methods: A retrospective analysis was conducted on 89 patients with multilevel cervical OPLL presenting with symptom-ossification mismatch treated between January 2020 and January 2024. According to the opening side, 41 patients underwent laminoplasty with the opening toward the side with more severe ossification (ipsilateral group), and 48 patients toward the side with more severe symptoms and signs (contralateral group). There was no significant difference in the baseline data between groups ( Results: There was no significant difference between groups in operation time, intraoperative blood loss, or length of hospital stay ( Conclusion: For patients with multilevel cervical OPLL with symptom-ossification mismatch, UODL provides similar improvement in clinical symptoms regardless of whether the opening side is directed toward the side with more severe ossification or toward the more symptomatic side. However, opening toward the side with more severe ossification may lead to more pronounced spinal cord morphological recovery and posterior shift, although the impact of this radiological advantage on long-term clinical outcomes requires further investigation.
