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
Introduction: Uniportal video-assisted thoracoscopic surgery (VATS) is widely used as a minimally invasive approach for pulmonary diseases. Although this technique reduces postoperative pain, acute postoperative pain remains clinically significant. This study aimed to evaluate the feasibility and advantages of thoracoscopic paravertebral block. Methods: This single-center prospective randomized comparative study included 228 consecutive patients who underwent uniportal VATS at our institution between August 2022 and June 2024. Patients were randomly assigned to Group A (122 patients; intraoperative thoracoscopic direct-vision transthoracic paravertebral block) or Group B (106 patients; preoperative ultrasound-guided thoracic paravertebral block). Perioperative data, postoperative pain scores, opioid rescue analgesic use, and postoperative complications were analyzed. Repeated-measures analysis of variance was used to assess differences in postoperative pain scores over time between the two groups. Results: A total of 228 patients underwent uniportal VATS pulmonary resection. No significant differences were observed between the two groups in terms of age, sex, pulmonary function, arterial blood gas analysis, surgical side, incision location, nodule size, nodule position, operative time, blood loss, drainage duration, length of hospital stay, tumor stage, or postoperative complications ( Conclusions: These findings indicate that thoracoscopic paravertebral block is safe and effective. Compared with ultrasound-guided approaches, it was associated with lower postoperative pain scores and reduced rescue tramadol requirements. Further validation through prospective randomized controlled trials is required.
