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 purpose was to describe cervical sagittal alignment in adolescent idiopathic scoliosis (AIS) compared to a normal group of adolescents and young adults, seeking for differences by Lenke type.
methodsRadiographs of 1779 AIS patients and 1115 controls were analyzed. Lenke types were determined. Spinopelvic parameters, thoracic kyphosis (TK), lumbar lordosis and sagittal vertical axis (SVA) CAM, C2, and C7 were measured. Cervical parameters included McGregor slope, C1-C2 and McGregor-C2 lordosis, C2-C7 lordosis (subdivided into cranial and caudal arches), C7 and T1 slopes. Cervical alignment patterns were classified as lordotic, kyphotic or sigmoid shapes.
resultsLenke 1, 2, 3 and 6 curves showed decreased C2-C7 and caudal arch lordosis associated with decreased C7 and T1 slopes and TK (p < 0.001) compared to normal. Cranial cervical parameters were comparable to the normal group. Lenke 5 patients demonstrated TK, C7 and T1 slopes, and cervical alignment parameters close to the normal group. In AIS, TK correlated with caudal cervical (r = 0.76) and C2-C7 lordosis (r = 0.52), but only weakly with cranial cervical parameters.
conclusionCervical sagittal alignment compensatory changes in AIS predominantly involve the caudal cervical segment and are closely related to TK, while cranial alignment remains close to normal, supporting horizontal gaze. As opposed to other AIS types with thoracic deformity, Lenke 5 patients had no cervical compensation, and sagittal alignment was close to normal. Distinguishing normative from pathologic compensation across AIS curve types may help optimize surgical planning and restoration of TK to indirectly improve cervical alignment.
