A comprehensive study of right and left inferior phrenic artery variations in 1000 patients with multidetector computed tomography angiography: an important study for HCC.

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
purposeTo investigate the anatomic variations in the origins of the right and left inferior phrenic arteries (IPAs) using multidetector computed tomography and to classify their combined variations.
methodsThis retrospective study included patients undergoing abdominal aorta angiography between January 2015 and October 2019. The RIPA and LIPA origins were evaluated both separately and combined on three-dimensional images. The variant patterns of the IPAs were determined and classified. The numerical evaluation of the data was performed with SPSS 21.
resultsIn total, 1000 patients (478 women, 522 men) were evaluated. The IPAs originated from a common trunk or a common root in 360 (36.00%) patients, while the IPAs originated independently without a common trunk in 609 (60.90%) patients. The most common combined variant detected in the present study was IPAs originating as a common trunk from the coeliac trunk in 197 (19.70%) patients; 14 (1.40%) patients had no inferior phrenic artery (IPA), and 17 (1.70%) patients had only one IPA.
conclusionFifty-two different types of variations in the combined origin of the inferior phrenic arteries were described in this study for the first time in the literature. Awareness of the anatomic variations in the IPAs, which is critical for hepatocellular carcinoma origins, may benefit various clinical procedures, such as transcatheter arterial chemoembolization, organ transplantations, laparoscopic surgical procedures, and radiological procedures.
