Variations in the Termination of the Popliteal Artery: A Multidetector Computed Tomography Angiography (CTA)-Based Retrospective Study.
Article in Cureus, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundComprehension of the intrucate anatomy and variations in the termination of the popliteal artery (PA) is increasingly essential for endovascular interventionists, plastic surgeons, vascular surgeons, and orthopedic surgeons, due to the rise in procedures like embolectomy, vascular grafting, free fibular flap surgery, and high-tibial osteotomy. Few studies from India have reported on the variant anatomy of PA termination, and none have used 128-slice tomography. This study aimed to observe the terminal branching pattern of the PA and the morphology of its terminal branches using 128-slice computed tomography angiography (CTA) and to analyze its relation to gender and laterality. METHODOLOGY: A retrospective review of CTA images of 181 lower extremities from 100 patients (137 males and 44 females), aged five to 75 years, was conducted.
resultsThe usual type I-A pattern was found in 75.69% of cases, while 24.31% exhibited variant patterns. Type III was the most common variation observed (19.34%), with type III-A being the most prevalent (11.05%). Types II-B and II-C were not observed. Among 84 bilaterally examined cases, 19.05% had unilateral variations and 15.48% had bilateral variations, with 8.33% showing bilaterally similar variations and 7.14% dissimilar variations. No significant difference in branching patterns was found between genders or sides. The mean length of the tibial-peroneal trunk (TPT) in the type I-A pattern was 3.00 ± 0.99 cm (right side: 3.21 ± 1.02 cm; left side: 2.82 ± 0.93 cm; males: 2.9 ± 1.00 cm; females: 3.37 ± 0.85 cm), with statistically significant differences between sides and genders. In the type II-A pattern, the mean TPT length was 7.16 ± 3.75 cm. An exceptionally long TPT (12.97 cm) was noted in one case of the III-B pattern.
conclusionThere is a high prevalence of variation in the termination pattern of the PA. Knowledge of these variations is crucial for any interventions in this region to avoid postoperative vascular complications and reduce patient suffering.
