High Prevalence of Arterial and Venous Corona Mortis Variants in Cadaveric Dissection.
Article in Cureus, 2025. 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
backgroundThe arterial or venous corona mortis (CM) is an anatomical vascular variant found in the retropubic area. It is an anastomosis between the external iliac system and the obturator vessels. This study focuses on morphometric analysis and the establishment of the prevalence of arterial and venous CM in the Mexican population. METHODOLOGY: A total of 108 hemipelves from human cadavers embalmed with a propylene-glycol solution were analyzed using a suprapubic approach. The abdominal viscera were mobilized to locate the common iliac arteries and veins, which were perfused with red latex for arteries and blue for veins. The vessels of the internal iliac system were identified and dissected, and their morphological characteristics, pattern of variation, and laterality were examined. Measurements included caliber, length, and distance between the CM and the pubic symphysis, using an electronic Vernier caliper for all measurements. Each measurement was performed in triplicate and is presented as mean ± standard error.
resultsOf the studied hemipelves, 14 were female, and 94 were male. A morphometric analysis was performed, where we found that 32 (29.6%) of the hemipelves did not present any arterial variants and only 11 (10.1%) did not show a venous variant. Accordingly, this study found a prevalence of 76 (70.4%) for arterial variants and 97 (89.9%) for venous variants.
conclusionsThe frequency of CM had not been reported in the Mexican population; however, we found a higher prevalence (48%) of CM than previously reported (36%).
