Anatomical Variations of the Vermiform Appendix.

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
objectiveThe aim of the present work is to systematically review and present the existing literature on anatomical variations of the appendix.
methodsDetailed research was conducted in the PubMed medical database, using the terms "Appendix" AND "Anatomical variations", and 74 articles were initially revealed. After the application of the inclusion and exclusion criteria, all the non-related articles were excluded, and thus 40 articles were finally selected. DISCUSSION: The data analysis suggests that the location and form of the appendix may significantly vary among individuals. Common anatomical variations concerning its location include retrocecal, pelvic, retro-ileal, pre-ileal, prececal and paracecal appendices. The first two variants are the most common, although there is a discrepancy regarding their exact incidence. Rarely, the appendix may be intracecal, intramural, subhepatic or located in the left abdomen; mismatches of the McBurney guide point with the base of the appendix are also recorded. Concerning the appendix's form, several variations in the length, diameter, shape and number of appendages (doubling, tripling) may be present.
conclusionsAs evident from the presentation of the results, the vermiform appendix presents a wide variety and number of anatomical variations. The latter are of particular clinical importance and should be known to doctors - especially surgeons - to avoid complications in clinical practice.
