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

STUDY

designRetrospective study. PURPOSE: This study was undertaken to compare the patterns of syringomyelia in patients with presumed idiopathic and congenital scoliosis. OVERVIEW OF LITERATURE: The incidence of neuraxial anomalies presenting as idiopathic scoliosis ranges from 2% to 14%; the common ones are idiopathic syringomyelia (IS) and Chiari malformation type 1 (CM1) with syringomyelia. Some authors have speculated that scoliosis is caused by the asymmetrical compression of anterior horn cells by a syrinx, which causes an imbalance of the trunk musculature. In congenital scoliosis, syringomyelia is the second commonest cord anomaly, and the deformity progression depends upon the underlying vertebral abnormality, the location of the abnormality, and the age of patient, and is independent of the intraspinal anomaly.

methodsWe analyzed the radiological records of 44 consecutive patients with scoliosis and syringomyelia. Of these 44 patients, 13 had IS, 12 had CM1, and 19 had congenital scoliosis. The radiographs were evaluated to determine the curve magnitude, sagittal alignment, side of convexity, and type of vertebral anomaly, if any. T1- and T2-weighted magnetic resonance imaging of the whole spine was analyzed to determine the presence of craniovertebral anomalies, syrinx length, syrinx diameter, and syrinx-cord ratio (SCR).

resultsThe frequency of left convex curves was 26.1%, with no significant differences across the three groups. The mean length of the syrinx was 7.2±4.9 vertebral levels, and the mean SCR was 0.39±0.2. The mean syrinx length was significantly higher in patients with CM1 and IS, compared to patients with congenital scoliosis. The mean SCR was highest in patients with CM1. In congenital scoliosis, syringomyelia was seen most frequently in patients with a failure of formation, and 63.2% had concomitant cord anomalies.

conclusionsSyrinxes were smaller in size and length in patients with congenital scoliosis, and are distinct from those seen in IS and CM1.
