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
STUDY
designRetrospective, observational study.
objectiveThis study aimed to evaluate the clinical efficacy of cervical posterior laminectomy with lateral mass screw internal fixation combined with 1-2 levels of laminoplasty in patients with severe complex cervical spondylotic myelopathy. SUMMARY OF BACKGROUND DATA: In this single-center retrospective observational study, data collected from 15 patients who underwent modified cervical posterior laminectomy with lateral mass screw internal fixation (modified PLF group) were compared with those from 45 patients who underwent standard cervical posterior laminectomy with lateral mass screw internal fixation (PLF group) during the same period.
methodsThe cervical curvature, Japanese Orthopaedic Association (JOA) score, visual analog scale (VAS), neck disability index (NDI), Odom's grade, and development of C5 nerve palsy were compared preoperatively and postoperatively. A power analysis was conducted to determine the sample size required to detect clinically significant differences between the groups. Based on an expected effect size of 0.5, a significance level (α) of 0.05, and a power (1-β) of 80%, the analysis indicated that a minimum of 60 patients per group would be needed. The mean follow-up period was 3.5 years.
resultsA significant reduction in the extent of cervical kyphosis ( P <0.05) was observed at the last follow-up in both groups. There were no significant differences in the JOA score, VAS, and NDI, all of which significantly improved in both groups. The rates of excellent and good Odom's grading (100% and 88.89% in the modified PLF and PLF groups, respectively) and the incidence of C5 nerve palsy (0% and 11.11% in the modified PLF and PLF groups, respectively) were significantly different between the 2 groups ( P <0.05). The power analysis confirmed that the study was adequately powered to detect significant differences in cervical curvature and clinical outcomes, although the smaller sample size of the modified PLF group (n=15) may have limited the ability to detect smaller but clinically meaningful differences in secondary outcomes.
conclusionsModified cervical posterior laminectomy with lateral mass screw internal fixation achieved improved clinical outcomes after medium-to-long-term follow-up in patients with severe and complex cervical spondylotic myelopathy. It can stabilize the cervical spine, fully decompress the spinal canal, and prevent excessive backward drifting of the cervical spinal cord, thereby reducing cervical spinal cord injury and C5 nerve palsy.
