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

introductionThe aim of the present meta-analysis was to provide the most up-to-date and evidence-based results regarding the morphometric properties of the lumbar vertebrae.

methodsMedical databases such as PubMed, Scopus, Embase, Web of Science, Google Scholar, and Cochrane Library were searched through.

resultsThe results of this meta-analysis were established based on a total of 1481 patients. New results were established in 27 categories for each lumbar vertebra separately. The findings from this study reveal that the width of the spinal canal progressively increases towards the lower end of the lumbar spine (L1 = 22.04 mm, L5 = 26.46 mm). Additionally, the transverse processes exhibit a similar trend, widening as they approach the lower lumbar vertebrae (L1 = 68.08 mm, L5 = 85.91 mm). The pedicle height decreased from L1 to L4, with an increase observed at L5 (14.73 mm). No significant differences were observed between the measurements of the left and right pedicles.

conclusionThe presented results provide physicians with normative morphometric data on the lumbar vertebrae. Having adequate knowledge of the anatomy of the lumbar vertebrae may be of immense use for surgeons performing various spinal surgeries, such as pedicle screw fixation, percutaneous endoscopic transforaminal discectomy, or lumbar disc replacement.
