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

purposeThis study clarified the influence of the splenic vein (SV) on delayed gastric emptying (DGE) in patients who underwent pancreaticoduodenectomy (PD) combined with portal vein (PV) and superior mesenteric vein (SMV) resections.

methodsA total of 147 patients who underwent open subtotal stomach-preserving pancreaticoduodenectomy (SSPPD) with PV/SMV resection were included in this study and classified into two groups: SV resection (n = 101) and preservation (n = 46). The incidence of DGE was compared between groups. Univariate and multivariate analyses were used to identify the risk factors for DGE.

resultsThere was no significant difference in the incidence of Grade B or C DGE between the SV resection and preservation groups (19.8 vs. 19.6%, respectively; p = 0.973). Multivariate analysis revealed that intra-abdominal abscess (odds ratio, 3.355; 95% confidence interval, 1.324-8.500; p = 0.011) was the only independent risk factor for DGE.

conclusionSV resection did not affect the incidence of DGE after SSPPD with PV/SMV resection. There may be no need to insist on preserving the veins associated with gastric venous flow out of concern for DGE.
