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

purposeThe aim of the study was to analyze four radiographic methods of calculating the loss of body height associated with scoliosis.

methodsThirty patients with right thoracic idiopathic scoliosis were examined with standing postero-anterior radiographs. Cobb angles of the upper thoracic, main thoracic and lumbar curves were measured. The loss of body height due to scoliosis was measured directly on the radiographs and then calculated using the methods of Bjure, Kono, Stokes and Ylikoski, respectively. The reproducibility of calculations was tested. Detailed analysis of two patients with similar Cobb angle but different trunk height was performed.

resultsThe mean Cobb angle of the main thoracic curve was 46° (21°-74°). The mean loss of body height was 23 mm (11-43 mm) calculated by method of Bjure, 7 mm (-24 to 46 mm) by Kono, 20 mm (5-47 mm) by Stokes, 14 mm (3-36 mm) by Ylikoski, versus 18 mm (3-50 mm) measured directly on radiographs. The overall difference between the loss of body heights was significant (p < 0.0001), with significant differences in pairs for: Bjure versus Kono (p < 0.0001), Stokes versus Kono (p = 0.0002), Kono versus measured (p = 0.0061) and Bjure versus Ylikoski (p = 0.0386). Strong linear correlation between the methods was found (r ≥ 0.92; p < 0.0001). High reproducibility of height loss calculations was noticed. The two patients with similar Cobb angle and different trunk height revealed similar height loss calculated, while different loss measured on radiographs.

conclusionsThere existed no overall agreement between the four methods of calculation of the loss of body height associated with scoliosis. Calculations based on the Cobb angle produced inaccuracy and could be supplemented with data considering trunk size.
