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
BACKGROUND AND
objectivesLateral lumbar interbody fusion techniques have advanced toward minimally invasive, anatomy-preserving approaches that enhance sagittal alignment and reduce perioperative morbidity. The most common existing approaches-the prone transpsoas and oblique lumbar interbody fusion-offer distinct advantages with opposing limitations. This manuscript describes a novel prone angled transpsoas (PAT) technique that combines the ergonomic and sagittal benefits of prone positioning with a navigated oblique/angled approach and direct lateral working corridor. This technique aims to simplify lateral surgery and minimize plexus and vascular risk, while enabling single-position surgery with the help of image-guidance navigation and neuromonitoring.
methodsThe operative technique for a PAT approach is described. The rationale for this approach and a representative case example are reviewed.
resultsA 73-year-old woman with grade 1 L4-L5 anterior spondylolisthesis and bilateral radiculopathy underwent PAT lateral lumbar interbody fusion with concurrent percutaneous posterior fixation. With the use of neuromonitoring and navigation, PAT approach combined the advantages of prone transpsoas surgery (increased lordosis, more posterior lumbar plexus, single-position surgery, minimized risk of bowel and vascular injury) with the navigated anterior angled approach (oblique lumbar interbody fusion/anterior-to-psoas) that may minimize risk of plexus injury.
conclusionThe authors' early experience with the described PAT technique suggests that it is not only feasible but also offers advantages. This technique leverages prone techniques with an oblique angled approach while making use of navigation and neuromonitoring when creating a lateral corridor, which removes the need to work obliquely. The use of navigation and neuromonitoring improves the ability to safely work laterally. Further follow-up studies of this technique are ongoing.
