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
objectivesThe global alignment and proportion (GAP) score was designed to predict mechanical complications (MC) following adult degenerative scoliosis (ADS) surgery. Despite its foundational role, its clinical application has been hindered by the labor-intensive nature of manual calculations, inefficiencies, and the complexity of evolving modified versions. This study aimed to develop an innovative deep-learning-powered tool for vertebrae detection and automated computation of editable, multi-version GAP scores.
methodsLeveraging a robust dataset of 3,485 spinal X-rays (both screw-containing and screwless images), we trained and tested a vertebrae detection model. Automatic extraction of sagittal parameters was seamlessly integrated into a multi-version GAP scoring system. A retrospective cohort of ADS surgery patients was used to validate various GAP score versions, including a novel ethnicity-age-gender-adjusted C-GAP (EAGA C-GAP) score.
resultsOur model demonstrated robust detection performance (mean average precision: 0.780 for screw-containing images and 0.732 for screwless images). The automatic GAP scoring system supports editable versions, with the EAGA C-GAP achieving superior predictive accuracy for MC (area under the curve, AUC = 0.627), outperforming the original and ethnicity-adjusted versions. Among GAP score components, relative lumbar lordosis (RLL) emerged as the most pivotal predictor, while the lordosis distribution index (LDI) contributed the least.
conclusionsThis groundbreaking integration of artificial intelligence into GAP score computation represents a transformative advancement in ADS surgery outcome prediction. By enhancing efficiency and clinical predictive accuracy, the optimized EAGA C-GAP score sets a new standard for individualized prediction tailored to the Chinese population, reflecting the crucial role of ethnicity, age, and gender considerations in surgical outcome predictions.
