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
purposeDysfunction of the remnant liver after a hepatectomy is caused by microthrombus formation due to endothelial cell (EC) damage. This study evaluated the effect of prostaglandin I(2) (PGI(2)) on the expression of thrombomodulin (TM), a marker for the anticoagulant properties of ECs, using cultured human umbilical vein endothelial cells (HUVECs), and using a canine extensive hepatectomy model.
methodsThe presence of PGI(2) receptors was confirmed on HUVECs by reverse transcription-polymerase chain reaction, and the effect of the PGI(2) analog on TM expression on HUVECs was determined by an enzyme-linked immunosorbent assay. Twenty mongrel dogs were divided into four groups comprising a sham operation, 70% hepatectomy, 84% hepatectomy, and 84% hepatectomy, with the administration of the PGI(2) analog, respectively, and TM expression in the liver, spleen, pancreas, kidney, lung, portal vein, and intestine was determined immunohistochemically.
resultsThe TM expression on HUVECs was upregulated by the PGI(2) analog. The TM expression on ECs in the hepatic sinusoids and splenic sinus were markedly decreased after the 84% hepatectomy, but such damage was markedly mitigated following an 84% hepatectomy with administration of the PGI(2) analog.
conclusionsAn extensive hepatectomy induced severe EC damage not only in the hepatic sinusoids but in the splenic sinuses as well. Prostaglandin I(2) prevented damage to these ECs, suggesting that PGI(2) improves the microcirculation in the remnant liver.
