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
purposeThe increased interspinous distance ratio (ISDR) at the fracture site in plain X-ray is useful as an indicator of injury of the posterior ligament complex in thoracolumbar fractures.
methods154 patients of thoracolumbar junctional fracture (T12, L1, L2) were subjects for this study. The sensitivity, specificity, accuracy of MRI was measured by comparing the surgery findings for the two analysis groups: one in which indeterminate cases were included in the intact group and another in which the indeterminate cases were included in the ruptured group. Sensitivity, specificity, accuracy of ISDR (measured in lateral decubitus X-ray) were measured after dividing patients into 3 groups (110, 120, 130 % increased).
resultsMRI's sensitivity, specificity and accuracy were 70.8, 100, and 80.5 %, respectively, when the indeterminate was assumed to have intact PLC. After assuming the indeterminate to have ruptured PLC, sensitivity, specificity and accuracy were 99.1, 52.4, and 85.7 %, respectively. In 53 cases with indeterminate MRI reading, sensitivity, specificity and accuracy were 81.2, 76.2, and 79.2 % %, respectively.
conclusionIn this study, in cases where it was difficult to make a diagnosis of the injury in the posterior ligament complex, based on the interspinous distance ratio (ISDR) of 120 % measured in plain X-ray in a lateral decubitus position, the sensitivity was 81.3 %, the specificity was 76.2 %, and the accuracy was 79.2 %. Therefore, measuring the ISDR will be helpful in determining whether surgical treatment is required in patients with thoracolumbar injury.
