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.
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
backgroundThe posterior longitudinal ligament plays a key role in spinal stability. The purpose of this study was to determine the injuries of the posterior longitudinal ligament (PLL) in thoracolumbar burst fractures. PATIENTS AND
methodsPatients suffering a thoracolumbar burst fracture from January 2011 to December 2015 were divided into an intact group and a disrupted group according to the status of the PLL. Mid-sagittal canal diameter, width and height of bone fragments, inversion angle and horizontal rotation angle of bone fragments and local kyphosis angle were measured. Anterior, middle and posterior vertebrae compression ratio, mid-sagittal diameter compression ratio, ratio of height of bone fragments occupying the posterior wall of the injured vertebral body and ratio of the width of bone fragment occupying the transverse canal diameter were calculated.
resultsA total of 95 patients were included in the study including 52 patients in the intact group and 43 patients in the disrupted group. There were significant differences on anterior and posterior vertebrae compression ratio, mid-sagittal diameter compression ratio, inversion angle and horizontal rotation angle of bone fragment (P 0.05) between the two groups. Injury of the PLL showed a positive correlation with the mid-sagittal diameter compression ratio and inversion angle of bone fragment (P 0.05).
conclusionThe mid-sagittal diameter compression ratio and inversion angle of bone fragment can be used to assess the status of the PLL in thoracolumbar burst fractures. When the mid-sagittal diameter compression ratio was 52% and the inversion angle of the bone fragment was 33° the PLL was likely to be disrupted.
