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

As has been known for many decades, oxaloacetate (OAA) is a very potent inhibitor of succinate dehydrogenase (SDH). However, the phenomenon has received little attention for several reasons to be discussed. Although the interaction between OAA and the structure of SDH has been scrutinized, there has been little attention to the mechanism underlying OAA inhibition of SDH in respiring mitochondria or to its functional implications. In recent years, we have used more advanced methodology to examine these issues. OAA is unstable and therefore very difficult to detect by mass spectroscopy. Hence, we used a novel NMR approach to assess OAA in mitochondria of muscle, brown adipose tissue, and liver under active respiratory conditions. We also used a modification of existing technology to assess mitochondrial respiration in states apart from the extremes of
