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

Inactivation and initial interrogation of key oxygenase CmmOIV of the biosynthetic pathway of chromomycin A(3) in Streptomyces griseus ssp. griseus revealed that a completely methylated and acetylated prechromomycin is the preferred substrate of this enzyme. This suggests that the three sugar decoration reactions, two O-acetylations and an O-methylation, which were previously believed to occur as the final steps of chromomycin A(3) biosynthesis, indeed take place prior to the CmmOIV reaction. Upon inactivation of CmmOIV, four new compounds accumulated; the fully decorated prechromomycin and its incompletely acetylated precursor along with a diketoprechromomycin-type compound were fully characterized and assayed with CmmOIV.
