Factors influencing the quality of life following posterior approach surgical treatment in adolescents with idiopathic scoliosis: A 2-year follow-up study.

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
purposeSurgical intervention is the preferred approach to prevent further progression of deformity for patients with adolescent idiopathic scoliosis (AIS); among existing surgeries, posterior spinal fusion is predominant. The minimal clinically important difference (MCID) of the total score of the Scoliosis Research Society (SRS)-22r questionnaire is an increase of ≥ 0.4 in surgically treated patients. However, to the best of our knowledge, there is no research exploring the factors influencing SRS-22r total scores exceeding MCID at 2 years postoperatively.
methodsPatients who underwent posterior spinal fusion between February 2019 and November 2023 and had a minimum follow-up duration of > 2 years were included. The radiological data and SRS-22r scores were assessed preoperatively and postoperatively. Based on the SRS-22r total scores, the patients were divided into two groups: ‘I’ = Improvement group (∆ Score ≥ 0.4) and ‘NI’ = Non-improvement group (∆ Score < 0.4). Demographic characteristics, radiographic data, and SRS-22r scores were analyzed using chi-square tests and t-tests for comparison. Multivariate logistic regression analysis was used to determine influencing factors.
resultsA total of 66 patients with AIS underwent posterior spinal fusion surgery were included in the study. The major Cobb angle decreased from 52.9 ± 12.3° preoperatively to 12.3 ± 8.6° (p < 0.001) at 2 years postoperatively, while the SRS-22r total score improved from 3.9 ± 0.4 to 4.2 ± 0.5 (p < 0.001). Overall, 32 of 66 of patients (48.5%) achieved MCID. Preoperatively, the Improvement group trended toward a larger Cobb angle (p = 0.042). Postoperatively, patients who achieved a greater Cobb angle correction in degrees were more likely to attain the MCID (p = 0.003).
conclusionPostoperative MCID attainment in patients with AIS is influenced by both the preoperative Cobb angle and the degree of its surgical correction.
