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

backgroundButyrate is the main nutrient for the colonocytes but the effect of the fraction reaching the liver is not totally known. A decrease in tissue ATP content and increase in respiration was previously demonstrated when livers were perfused with short-chain fatty acids (SCFA) such as butyrate, or octanoate. In fed rats the oxidative phosphorylation yield was determined on the whole isolated liver perfused with butyrate in comparison with acetate and octoanoate (3 mmol/L). The rate of ATP synthesis was determined in the steady state by monitoring the rate of ATP loss after inhibition of (i) cytochrome oxidase (oxidative phosphorylation) with KCN (2.5 mmol/L) and (ii) glyceraldehyde 3-phosphate dehydrogenase (glycolysis) with IAA (0.5 mmol/L). The ATP flux, estimated by 31P Nuclear Magnetic Resonance, and the measured liver respiration allowed the ATP/O ratio to be determined.

resultsATP turnover was significantly lower in the presence of butyrate (0.40 +/- 0.10 micromoles/min.g, p = 0.001, n = 7) and octanoate (0.56 +/- 0.10 micromoles/min.g, p = 0.01, n = 5) than in control (1.09 +/- 0.13 micromoles/min.g, n = 7), whereas perfusion with acetate induced no significant decrease (0.76 +/- 0.10 micromoles/min.g, n = 7). Mitochondrial oxygen consumption was unchanged in the presence of acetate (1.92 +/- 0.16 vs 1.86 +/- 0.16 for control) and significantly increased in the presence of butyrate (p = 0.02) and octanoate (p = 0.0004) (2.54 +/- 0.18 and 3.04 +/- 0.15 micromoles/min.g, respectively). The oxidative phosphorylation yield (ATP/O ratio) calculated in the whole liver was significantly lower with butyrate (0.07 +/- 0.02, p = 0.0006) and octanoate (0.09 +/- 0.02, p = 0.005) than in control (0.30 +/- 0.05), whereas there was no significant change with acetate (0.20 +/- 0.02).

conclusionButyrate or octanoate decrease rather than increase the rate of ATP synthesis, resulting in a decrease in the apparent ATP/O ratio. Butyrate as a nutrient has the same effect as longer chain FA. An effect on the hepatic metabolism should be taken into account when large quantities of SCFA are directly used or obtained during therapeutic or nutritional strategies.
