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

purposeOverweight was found to be a negative predictor of brace effectiveness for adolescent idiopathic scoliosis (AIS), with a threefold higher risk of progression than in normal weight patients. The aim of this study is to investigate overweight, as a predictor of brace results in AIS patients.

methodsDesign: retrospective cohort study. POPULATION: 351 AIS patients (306 females), mean age 12.9 ± 1.4, mean Cobb 35.6 ± 11.4°, mean ATR 11 ± 4.3°, BMI 19.7 ± 3, median Risser: 2. INCLUSION CRITERIA: no previous treatment, full-time prescription of brace at first visit (18-23 h per day), scoliosis physiotherapeutic exercise according to the SEAS protocol associated. OUTCOME: improved, progressed, and stable according to the 5° Cobb agreed threshold. STATISTICS: a stepwise linear regression was used to look for the effect of BMI as a predictor of result. A Chi-square test and logistic regression were used for the overweight category (BMI ≥ 85th percentile). Control for possible confounders was applied.

resultsBMI is poorly correlated with final results. Confounders' adjustment did not change the correlation, and the predictive model explained about 10% of the result. Brace results were not statistically different in overweight and normal weight: 44 vs 52% improved, 52 vs 41% stable, and 3 vs 7% worsened, respectively. DISCUSSION: Brace results were similar in overweight and normal weight subjects. These findings subvert the previous results and disprove the role of overweight as a negative predictor. Treatment management, brace type and effectiveness may play a major role in reducing the risks of scoliosis progression.
