Cross-cultural adaptation, reliability and validity of the Greek version of the Spinal Appearance Questionnaire (SAQ) in patients with adolescent idiopathic scoliosis.

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
purposeThe Spinal Appearance Questionnaire (SAQ) is a widely validated tool for assessing perceptions of spinal deformity in adolescent idiopathic scoliosis (AIS) patients. This study aimed to develop and validate a Greek version of the SAQ (GR-SAQ).
methodsA cross-cultural adaptation of the SAQ following international guidelines was performed. Internal consistency and test-retest reliability were evaluated. Convergent validity was assessed by correlating the GR-SAQ with the Appearance domain of Scoliosis Research Society-22 (SRS-22) and the Cobb angle with the Trunk Shift domain of GR-SAQ. Divergent validity was examined through the relationship between GR-SAQ, patient characteristics, and clinical measures including Cobb angle, DIERS Formetric 4D angle, and scoliometer readings.
resultsThe study included 61 AIS patients (52 females, 13.91 ± 2.57 years, 25.33 ± 10.14° Cobb angle). GR-SAQ exhibited good internal consistency (Cronbach's α = 0.794) and excellent test-retest reliability (ICC = 0.931, 95%CI: 0.880-0.960). Correlations between GR-SAQ and SRS-22 showed a low-to-moderate negative correlation (r = -0.351, p = 0.006). The Trunk Shift domain moderately correlated with the Cobb Angle (r = 0.393, p = 0.002). Divergent validity analyses did not demonstrate statistical significance (p > 0.05).
conclusionThe GR-SAQ is a valid and reliable tool for evaluating spinal deformity perception in Greek AIS patients.
