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
Purpose: To evaluate the long-term efficacy and safety of multi-segment cortical bone trajectory screws for treating mild adult degenerative scoliosis with stenosis among the elderly. Patients and Methods: From January 2018 to December 2019, a total of 41 patients of mild adult degenerative scoliosis with stenosis underwent posterior lumbar decompression, bone graft fusion, and internal fixation, which were retrospectively divided into pedicle screw (PS) group and cortical bone trajectory (CBT) screw group according to different internal fixation methods. The operation time, intraoperative blood loss, immobilization, and length of hospital stay were compared between the two groups. The visual analog score (VAS) of low back and leg pain, Oswestry disability index (ODI), Cobb angle, lumbar lordosis (LL) angle, apex vertebral translation (AVT), coronal balance distance (CBD) and sagittal vertical axis (SVA) were compared between the two groups preoperatively and 6 months, 1 year, 5 years postoperatively. Perioperative and follow-up complications were observed. Results: The CBT group was superior to PS group in operation time, intraoperative blood loss, immobilization, length of hospital stay ( Conclusion: Multi-segment cortical bone trajectory screws is a safe and effective treatment option for mild adult degenerative scoliosis with stenosis among the elderly. This technique features miniinvasive trauma and quick recovery, which might lead to improved long-term quality of life and a reduction in screw loosening and adjacent segment disease rates.
