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
backgroundPortal vein thrombosis (PVT) leads to portal hypertension (PH) with its sequelae. Computed tomography spleno-mesenterico-portography (CT-SMPG) combines sequential CT spleno-portography and CT mesenterico-portography. CT-SMPG comprehensively illustrates the venous hemodynamic changes due to PH.
objectiveTo assess the effects of PV confluence thrombosis (PVCT) and liver cirrhosis on venous blood flow characteristics of patients with PVT.
methodCT-SMPG was performed in 21 patients with chronic PVT. CT-SMPG was compared to standard contrast-enhanced CT (CECT) and gastroscopy concerning the patency of splanchnic veins, varices and venous congestion.
resultsPVCT had a significant effect on perfusion patterns: in patients without PVCT, esophageal varices (EV) and gastric varices were supplied by either the splenic vein (SV), the superior mesenteric vein (SMV), or both. In patients with PVCT, EV and gastric varices were mostly supplied by the SV (
conclusionsIn CT-SMPG, patients with PVCT showed different venous hemodynamics to patients without PVCT, and this can serve as a basis for selecting therapy options.
