Inhibitory effect of tumor necrosis factor α on gluconeogenesis in perfused rat liver.

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
Tumor necrosis factor α (TNFα) is a cytokine involved in many metabolic responses in both normal and pathological states. Considering that the effects of TNFα on hepatic gluconeogenesis are inconclusive, we investigated the influence of this cytokine in gluconeogenesis from various glucose precursors. TNFα (10 μg/kg) was intravenously injected in rats; 6 h later, gluconeogenesis from alanine, lactate, glutamine, glycerol, and several related metabolic parameters were evaluated in situ perfused liver. TNFα reduced the hepatic glucose production (p < 0.001), increased the pyruvate production (p < 0.01), and had no effect on the lactate and urea production from alanine. TNFα also reduced the glucose production (p < 0.01), but had no effect on the pyruvate production from lactate. In addition, TNFα did not alter the hepatic glucose production from glutamine nor from glycerol. It can be concluded that the TNFα inhibited hepatic gluconeogenesis from alanine and lactate, which enter in gluconeogenic pathway before the pyruvate carboxylase step, but not from glutamine and glycerol, which enter in this pathway after the pyruvate carboxylase step, suggesting an important role of this metabolic step in the changes mediated by TNFα.
