1 · What the graph read from it

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.

2 · The registry

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

purposeTo evaluate the effectiveness of underarm bracing alone versus combined underarm bracing with Schroth methods for radiographic shoulder imbalance in adolescent idiopathic scoliosis (AIS) patients and whether radiographic changes translate into patient-perceived changes.

methodsThis retrospective study included moderate AIS patients with radiographic shoulder imbalance, categorized into brace-alone and combined (brace with Schroth methods) groups. Shoulder balance was assessed using standardized radiographs at baseline, first follow-up, and final follow-up. Primary outcomes were changes in T1 tilt (medial) and clavicle angle (lateral); secondary outcomes included additional radiographic measures. Associations between changes in primary radiographic parameters and patient-reported shoulder appearance were evaluated using the revised 22-item Scoliosis Research Society questionnaire appearance domain. Between-group differences were analyzed using analysis of covariance, with linear mixed-effects models for supplementary analyses; correlations were assessed using Pearson's or Spearman's coefficients.

resultsA total of 54 patients were included, with 25 in the combined group and 29 in the brace-alone group. The combined group showed greater improvement in lateral shoulder balance, with larger ΔCA from baseline to final follow-up (1.04°, p = 0.026) and a significant group × time interaction (p = 0.041). Medial shoulder changes were comparable between groups. T1 tilt changes correlated with patient-reported appearance overall (r = 0.698, p = 0.037) and in the combined group (r = 0.917, p = 0.029), whereas clavicle angle changes did not.

conclusionsCombined bracing with Schroth methods improves lateral but not medial shoulder imbalance. Medial shoulder changes, not lateral, relate to patient-perceived appearance, highlighting the multidimensional nature of shoulder imbalance.
