1 · What the graph read from it

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.

2 · The registry

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

purposeThe splenic artery (SA) is the largest and most tortuous branch of the celiac trunk with a wide spectrum of variants, particularly in its terminal branches.

methodsThe current study presents a systematic review of the English literature on the SA variations, with emphasis on its terminal branching patterns.

resultsThirty cadaveric studies (3132 specimens) were included in the analysis. The SA originated from the celiac trunk in 97.2%, from the abdominal aorta in 2.1% and from the superior mesenteric or the common hepatic artery in 0.7% of cases. A suprapancreatic course was observed in 77.4%, retropancreatic course in 17.8%, anteropancreatic course in 3.4% and intrapancreatic course in 1.3%. In the majority of cases, the SA bifurcated into superior and inferior lobar arteries (83.4%), with trifurcation and quadrifurcation in 11.3% and 2.7%, respectively. Five or more lobar branches (1.4%) and a single lobar artery (1.2%) were rarely identified. The distributed branching pattern was found in 72.7%, whereas the magistral pattern in 26.9%. The inferior and superior polar arteries (IPA and SPA) were found in 47.7% and 41.7% of cases, respectively, while polar artery agenesis was recorded in 28.2%. The SPA usually originated from the SA main trunk (53.6%) or from the superior lobar artery (33.1%). The IPA emanated mainly from the left gastroepiploic artery (53%), from the SA (23.5%) or the inferior lobar artery (21.9%). Intersegmental anastomoses between adjacent arterial segments were identified in 14.2%.

conclusionKnowledge of the SA aberrations is important for surgeons and radiologists involved in angiographic interventions.
