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

objectivesClassification methods that are currently being used for clinical decision making in thoracolumbar fractures, are limited by reproducibility and prognostic value. Additionally, they do not include kyphosis. As a posttraumatic kyphosis is related to persistent pain, it is of importance to determine a risk of posttraumatic kyphosis based on fracture type and patient characteristics. PURPOSE: To determine risk factors (AO classification, age, gender, localization) that may lead to progressive kyphosis after a thoracolumbar fracture. MATERIALS AND

methodsRetrospective radiographic analysis of a consecutive patientcohort that presented in our clinic with a traumatic fracture of the thoracolumbar spine between 2004 and 2011. Cobb angle, Gardner angle, vertebral compression angle and anterior vertebral body compression were measured on plain radiographs, direct post-trauma and at follow-up.

resultsAge and localization are not significantly correlated, but there seems to be an increased risk of progression of kyphosis in age > 50 years and fractures localized at Th12 or L1. A3 type fractures are significantly more at risk for posttraumatic kyphosis compared to A1 and A2 type fractures. 30-50% of the A3 type fractures have an end Gardner angle and end vertebral compression angle of more than 20 degrees.

conclusionAO-type A3 fractures appear to be at risk of progression of kyphosis. Localization at Th12-L1 and age above 50 years seem to be risk factors for significant posttraumatic kyphosis. These findings should be used in patient counseling and a meticulous evaluation by weekly radiographs is recommended to determine the treatment strategy of thoracolumbar fractures.
