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
Significant variability exists among surgeons regarding planning methods for adolescent idiopathic scoliosis (AIS) surgery. Lenke et al. advocated the use of preoperative supine full-spine radiographs, but their accuracy in predicting intraoperative alignment remains debated. This study aimed to compare preoperative supine radiographs with intraoperative prone radiographs during AIS posterior fusion. A total of 139 patients undergoing AIS posterior fusion at a single center were prospectively studied. Frontal radiographic parameters from preoperative supine full-spine films were compared with those from prone radiographs at the beginning of surgery to verify the lower instrumented vertebra (LIV). Pearson correlation coefficients assessed the relationship between preoperative supine and intraoperative non-instrumented (NI) radiographs. Strong correlations were found for thoracic and lumbar Cobb angles (r > 0.8). The main thoracic angle decreased from 46° to 44° (mean difference 2°, p = 0.004), and the lumbar angle from 27° to 25° (mean difference 2°, p < 0.0001). The C7-Central Sacral Vertical Line (CSVL) correlation was weaker (r = 0.3). All curves showed significant reduction intraoperatively compared with preoperative supine films (p = 0.045 for thoracic and p = 0.03 for lumbar). The apical vertebral translation ratio (AVTMT/AVTL) showed no significant difference (p = 0.2). Preoperative supine radiographs reliably predict intraoperative alignment and are valuable for AIS surgical planning. However, parameters related to CSVL, LIV tilt, and Disc Wedging Angle (DWA) may be more influenced by positioning and soft-tissue release.
