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

We compared the cellular fatty acid profiles of Myxococcus xanthus cells grown in either a Casitone-based complex medium or a chemically defined medium. The cells grown in the complex medium had a much higher content of the abundant branched-chain fatty acid iso-15:0 and several other branched-chain species. The higher branched-chain fatty acid content of the cells grown in the complex medium was dependent on the esg locus, which encodes the E1alpha and E1beta components of a branched-chain keto acid dehydrogenase (BCKAD) multienzyme complex involved in branched-chain fatty acid biosynthesis. Cells grown in the complex medium were also found to have a higher level of esg transcription and more BCKAD enzyme activity than cells from the chemically defined medium. The level of esg transcription appears to be an important factor in the growth medium-dependent regulation of the M. xanthus branched-chain fatty acid content.
