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
purposeAdolescent idiopathic scoliosis (AIS) has a large impact on health-related quality of life (HRQoL) including poor psychosocial functioning, body image, and psychological distress. Surgical management for AIS is common; however, there is limited consensus on preoperative and intraoperative strategies to optimize HRQoL outcomes. Accurate prediction of postoperative outcomes can help inform preoperative counselling and shared decision-making. This study aimed to generate machine learning models (MLMs) using preoperative and intraoperative variables to predict the difference in HRQoL outcomes from preoperative assessment to two years following AIS surgery.
methodsA prospective, longitudinal, multicenter database was queried for AIS patients of Lenke 1 or 5 classification with two-year follow-up. MLMs were generated using preoperative and intraoperative variables to predict the difference in Scoliosis Research Society-22 (ΔSRS-22) questionnaire scores from preoperative assessment to two-year follow-up. MLMs were compared to a model that estimates the mean score by evaluating the mean squared error (MSE) and the fraction of times the prediction was within a predesignated value of the actual score (i.e., buffer accuracy).
resultsA total of 1,477 patients (84.6% female, 75.0% White) were included. The lowest MSE for each ΔSRS-22 outcome ranged from 0.18-0.48, while the highest 0.25-buffer, 0.5-buffer, 0.75-buffer, and 1-buffer accuracies for each ΔSRS-22 outcome ranged from 34.8%-53.4%, 56.8%-83.1%, 75.0%-94.6%, and 87.2%-97.3%, respectively. These MSEs and buffer accuracies outperformed mean estimates.
conclusionMLMs built using preoperative and intraoperative variables enabled prediction of the difference in HRQoL outcomes from preoperative assessment to two years following AIS surgery. Findings provide key insights into the feasibility of implementing MLMs as prognostic tools to counsel patients on expected outcomes of surgical management. Future work should implement additional surgeon, institution, and patient factors as model predictors to increase predictive accuracy of HRQoL outcomes and ultimately improve individualized patient care through data-driven patient counselling.
