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 The appendix is a vermiform structure with a variable position, length, and thickness. Imaging plays a critical role in diagnosing an inflamed appendix, with non-contrast computed tomography (NCCT) being an effective modality when ultrasound is inconclusive. This study evaluates the visibility and anatomical characteristics of a normal appendix using NCCT. Methods This retrospective descriptive study was conducted in the Radiology Unit of Teaching Hospital Jaffna, in Jaffna, Sri Lanka, from September 2023 to February 2024, following approval from the Institutional Ethical Review Committee of the hospital. Two hundred individuals were evaluated (past appendectomy patients were excluded). IBM SPSS Statistics software, version 26 (IBM Corp., Armonk, NY, USA) was used, with significance assessed at P ≤ 0.05. Results Males were 64.5%. The visibility rate was 89%. The most common positions were retrocecal (27.5%), retroileal (22%), and pelvic (21.5%). The mean length was 7.5 cm, with a base diameter of 6.6 mm, a mid-section of 6.2 mm, and a tip of 5.8 mm. Mean wall thickness was 2.6 mm, fecoliths were found in 15% of cases, and the mean distance of the base from McBurney's point was 3.32 cm. Conclusion NCCT can be used to assess the morphology, position, and presence of fecolith in equivocal cases of suspected appendicitis when ultrasound is inconclusive and contrast is contraindicated. The appendicular diameter and wall thickness can be used as evidence of inflammation. McBurney's point is a reliable anatomical guide during open appendicectomies. The presence of a fecalith itself is not a reliable indicator of appendicitis.
