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
introductionMagnetic resonance imaging (MRI) is the most appropriate imaging method to investigate low back pain. As low back pain is very common, a large number of MRI scans are performed.
objectiveTo evaluate the extraspinal findings and clinical effect of the T1-weighted spin echo (T1W SE) coronal sequence added to the lumbar MRI protocol for low back pain. MATERIALS AND
methodsIn 2015, we added a T1-weighted (T1W) coronal sequence to our routine lumbar MRI protocol. We retrospectively evaluated 969 lumbar MRI images for low back pain performed with this protocol. The extraspinal MRI findings obtained from them were then grouped as associated with low back pain (Category 1) and not associated with low back pain (Category 2). We also evaluated whether the recorded incidental extraspinal findings could be detected on conventional sagittal and axial images.
resultsNinety-six (63%) of the extraspinal findings were associated with low back pain (Category 1) and 56 (37%), Category 2. Seventy-eight percent of the extraspinal findings were detected only on coronal-T1W images and not on conventional images.
conclusionAdding coronal-T1W sequence to the routine protocol of lumbar MRI can help to identify extraspinal findings and guide clinical treatment.
