Sagittal spinopelvic parameters in children and adolescents: a retrospective cross-sectional radiographic study from Turkey.
Article in Pediatric radiology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundSagittal spinal parameters are used to assess upright alignment during growth.
objectiveTo describe sagittal spinopelvic parameters and assess their associations with age and sex in children and adolescents in Turkey. MATERIALS AND
methodsThis retrospective cross-sectional study at a single tertiary orthopedic center included 344 children aged 6-17 years (186 boys, 158 girls) who underwent clinically indicated standing full-spine radiography. Pelvic incidence, pelvic tilt, sacral slope, lumbar lordosis, thoracic kyphosis, sagittal vertical axis, cervical vertebra (C) 2 tilt, thoracic vertebra (T) 4 tilt, lumbar vertebra (L) 1 tilt, T4 pelvic angle, and L1 pelvic angle were assessed. Age-group comparisons and age- and sex-adjusted linear models were used.
resultsMean (standard deviation) pelvic incidence, pelvic tilt, sacral slope, lumbar lordosis, and thoracic kyphosis were 45.4 (12.3)°, 11.3 (6.9)°, 34.2 (10.4)°, 57.5 (13.8)°, and 46.0 (13.4)°, respectively; sagittal vertical axis was 46.6 (27.6) mm. C2, T4, and L1 tilts were 5.0 (2.9)°, 10.4 (4.6)°, and 9.0 (4.7)°; T4 pelvic angle and L1 pelvic angle were 4.1 (3.1)° and 3.4 (3.1)°. Lumbar lordosis showed the largest adjusted age coefficient (1.81°/year; 95% confidence interval (CI) 1.28-2.34; adjusted R
conclusionIn children and adolescents without radiographic spinal or pelvic deformity, lumbar lordosis had the clearest cross-sectional association with age. No statistically significant age-group differences were detected for T4 pelvic angle or L1 pelvic angle. These data provide clinically relevant standing-radiograph reference data for sagittal spinopelvic parameters.
