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

purposeSevere spinal curvature in early onset scoliosis (EOS) impairs pulmonary development and function. The treatment requires imaging to assess spine growth and pulmonary function. The purposes of this study were to determine if radiographic sagittal spinal length (SSL) correlates with pulmonary function testing (PFT) and to compare SSL with T1-T12 coronal height (CH) to guide definitive fusion in EOS patients.

methodsGrowth-friendly graduate EOS patients who underwent definitive spinal fusion and had postoperative PFT data were identified in a multi-center database. CH and SSL measurements were obtained from upright radiographs. The PFT results were compared between these measurements, using the percentage of the expected PFT value based on age, sex, and height (arm span).

resultsForty-four patients were included. The average age at definitive fusion was 12.1 years (range, 10 to 15) at a mean of 5.6 years after the growth-friendly procedure. The diagnoses were idiopathic scoliosis (22/44, 50%), congenital scoliosis (12/44, 27%), syndromic scoliosis (8/44, 18%), and neuromuscular scoliosis (2/44, 5%). 37.2% of patients had moderate pulmonary dysfunction (FVCp < 60%). SSL and CH were strongly correlated (r = 0.770, p < 0.001). Predicted FEV1 and FVC had statistically significant moderate correlation with SSL (FEV1 r = 0.438, p = 0.002; FVC r = 0.450, p < 0.001), and weak correlation with CH (FEV1 r = 0.207, p = 0.091; FVC r = 0.282, p = 0.033).

conclusionSSL strongly correlated with traditional CH measurements, averaging 10 mm longer (p < 0.001). SSL had a stronger correlation with PFT than traditional CH, suggesting that, by considering the sagittal plane, SSL may provide a better indicator than CH for determining the timing of definitive fusion in EOS patients.
