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

backgroundThe failing heart is energy starved with impaired oxidation of long-chain fatty acids (LCFAs) at the level of reduced CPT1 (carnitine palmitoyltransferase 1) activity at the outer mitochondrial membrane. Recent work shows elevated ketone oxidation in failing hearts as an alternate carbon source for oxidative ATP generation. We hypothesized that another short-chain carbon source, short-chain fatty acids (SCFAs) that bypass carnitine palmitoyltransferase 1, could similarly support energy production in failing hearts.

methodsCardiac hypertrophy and dysfunction were induced in rats by transverse-aortic constriction (TAC). Fourteen weeks after TAC or sham operation, isolated hearts were perfused with either the 4 carbon,

resultsTAC produced pathological hypertrophy and increased the fractional contributions of ketone to acetyl coenzyme-A production in the tricarboxylic acid cycle (0.60±0.02 sham ketone versus 0.70±0.02 TAC ketone;

conclusionsSCFAs are more readily oxidized than ketones in failing hearts, despite both bypassing reduced CPT1 activity and represent an unexplored carbon source for energy production in failing hearts.
