Ornithine alpha-ketoglutarate: could it be a new therapeutic option for sarcopenia?
Article in The journal of nutrition, health & aging, 2010. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
Our current knowledge on the causes of sarcopenia is still fragmentary. One of the most evident candidates to explain muscle loss in elderly includes imbalance in protein turnover, i.e. decreased muscle protein synthesis rate, notably in the post-prandial state. Nutritional strategies such as leucine supplementation, use of fast digested proteins or a pulse protein intake have been show to enhance the synthesis rate of muscle proteins in older individuals. Ornithine alpha-ketoglutarate (OKG) is a precursor of amino acids such as glutamine, arginine and proline, and increases the secretion of anabolic hormones, i.e. insulin and growth hormone. A beneficial anabolic action of OKG has been demonstrate in several pathological conditions associated with muscle loss. Therefore, OKG may be of a potential interest to modulate muscle protein metabolism and to maintain muscle mass during aging.
