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
backgroundChildren with neuromuscular scoliosis undergoing scoliosis surgery face substantial rates of complications. To mitigate surgical risks such as blood loss in pediatric patients with neuromuscular scoliosis, this study focuses on enabling instrumentation planning for their abnormal vertebral and pelvic anatomy and osteopenia. This study assessed the feasibility of an "ultralow-dose" CT (ULD CT) protocol without sedation in pediatric patients with neuromuscular scoliosis who often have comorbid movement disorders. Our prospective quality improvement study aims: (1) to determine if ULD CT without sedation is feasible in this patient group; (2) to quantify the radiation dose from ULD CT and compare it with preoperative spine radiographs (XR); and (3) to assess if ULD CT allows accurate anatomical assessment and intraoperative navigation given the prevalence of movement disorders.
methodsChildren with neuromuscular scoliosis underwent spine XR and ULD CT scans. Chart reviews assessed disease etiology and comorbidities. Radiation dose was quantified through Monte-Carlo simulations giving dose indices and effective dose, with statistical analysis done using a paired student's t -test (α=0.05). CT image quality was assessed for its use in preoperative planning and intraoperative navigation.
resultsFourteen patients (5 males, 9 females, average age 14±3 y) participated. One patient needed sedation due to autism spectrum disorder and global developmental delay. The radiation dose for spine XR was 0.5±0.2 mSv, and ULD CT was 0.6±0.1 mSv. There was no statistically significant difference in radiation doses between methods. All ULD CT scans had adequate quality for preoperative assessment of pedicle diameter and orientation, obstacles impeding pedicle entry, S2 Alar-Iliac screw orientation, and intraoperative navigation.
conclusionsULD CT without sedation is feasible for children with neuromuscular scoliosis. Radiation doses were comparable to standard radiographs. ULD CT provided accurate anatomical assessments and supported intraoperative navigation, proving beneficial despite movement disorders in these patients. LEVEL OF EVIDENCE: Level 2-Development of diagnostic criteria on basis of consecutive patients (with universally applied reference widely accepted standard).
