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 technical key points and effectiveness of ultrasonic bone scalpel-assisted anterior controllable antedisplacement and fusion (ACAF) for treating cervical ossification of the posterior longitudinal ligament (OPLL). Methods: Between June 2022 and December 2024, 11 OPLL patients underwent ultrasonic bone scalpel-assisted ACAF. The cohort included 8 males and 3 females, aged 49-74 years (mean, 56.7 years). The OPLL classification included 5 cases of mixed-type, 4 cases of segmental-type, and 2 cases of continuous-type cases. Ossification involved 2-5 spinal segments (mean, 3.2). Disease duration ranged from 2 to 18 months (mean, 6.2 months). The operation time, intraoperative blood loss, and complications were recorded. Pain improvement was assessed using the visual analogue scale (VAS) score, and neurological function was evaluated using Japanese Orthopaedic Association (JOA) score. Postoperative cervical CT and MRI were performed to measure spinal canal encroachment rate, spinal canal area, and spinal cord sagittal diameter. Results: All operations were successfully completed. The operation time ranged from 174 to 360 minutes (mean, 255.9 minutes). The intraoperative blood loss ranged from 170 to 530 mL (mean, 345.9 mL). The C Conclusion: For the treatment of cervical OPLL via ACAF, the intraoperative application of ultrasonic bone scalpel-assisted osteotomy enables precise vertebral groove creation and mobilization of the vertebra-ossification complex, thereby enhancing surgical safety and achieving satisfactory short-term effectiveness.
