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

objectiveSevere scoliosis is often accompanied by moderate-to-severe pulmonary dysfunction. Numerous surgical methods are available for the treatment of severe scoliosis, but the effect of each method on postoperative pulmonary function (PF) remains controversial. Apical region correction and global balance (ACGB) is an effective surgical strategy to treat severe scoliosis, using Schwab I-II osteotomies and simple one-stage surgery. Herein, we explore the effect of the ACGB surgical strategy on postoperative PF values in patients with severe scoliosis at 2-year follow-up.

methodsPatients who underwent ACGB for scoliosis between 2015 and 2020 were enrolled, PF and radiological outcomes were evaluated preoperatively and at 2-year follow-up. PF values included forced expiratory volume in 1 s (FEV1), forced vital capacity (FVC), and percent-predicted values (FVC% and FEV1%). Paired t-test, Pearson and Spearman correlation analyses, and multiple linear regression were used to analyze changes in PF values and associated factors.

resultsIn total, 36 patients (12 male and 24 female; mean age, 20.1 years) who underwent ACGB surgery were enrolled. Preoperative PF values showed restrictive ventilatory dysfunction. At 2-year follow-up, the PF values showed significant improvements. FVC, FEV1, FVC%, and FEV1% showed mean increases of 0.72, 0.68 L, 10.3%, and 9.8%, respectively. Changes in PF values were significantly correlated with age, thoracic height, preoperative FVC%, and preoperative FEV1%.

conclusionACGB significantly improves PF in patients with severe scoliosis at 2-year follow-up. The increased thoracic height may be crucial for improving PF values, while patients with poorer preoperative PF may show greater postoperative improvement.
