Dimensions of bony Kambin's triangle pertaining to endoscopic procedure.
Article in Medical journal, Armed Forces India, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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: Endoscopic procedures nowadays are successful, minimally invasive, and safer, with fewer intraoperative and postoperative complications and shorter hospital stays. Kambin's triangle (KT) is the three-dimensional configuration that is used as a transforaminal anatomical corridor for epidural steroid injections and endoscopic surgeries for various lumbar pathologies. This study aims to estimate the dimensions of KT and diameter of the cannula for the transforaminal surgical approaches using KT in the Chhattisgarh population. Methods: Seven human cadavers (three males and four females) were included in the study for observing KT. Dissection was done to carefully clear landmarks, including the vertebral bodies, intervertebral disc, exiting nerve root, and superior articular process. Base (a horizontal plane passing through the superior border of the caudal vertebra) and height (along the superior articular process of the inferior vertebra in line with the articular facet) were measured. Hypotenuse, semiperimeter of the triangle, area of triangle, diameter, and area of the inscribed circle were calculated. Results: Height, base, and inscribed circle diameter increased from L1-L2 to L4-L5 then decreased to L5-S1. There was no statistically significant difference between males and females. The safest admissible cannula diameter according to the current study that can be used at all levels in KT was 6.06 mm. Conclusion: This study provides the safest cannula size to be considered in the patients of the Chhattisgarh population during transforaminal approaches in the lumbar area. Minimally invasive surgery and shorter hospitalization are vital criteria to evaluate any surgery these days.
