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
Nitrogen fixation is tightly regulated in Rhodospirillum rubrum at two different levels: transcriptional regulation of nif expression and posttranslational regulation of dinitrogenase reductase by reversible ADP-ribosylation catalyzed by the DRAT-DRAG (dinitrogenase reductase ADP-ribosyltransferase-dinitrogenase reductase-activating glycohydrolase) system. We report here the characterization of glnB, glnA, and nifA mutants and studies of their relationship to the regulation of nitrogen fixation. Two mutants which affect glnB (structural gene for P(II)) were constructed. While P(II)-Y51F showed a lower nitrogenase activity than that of wild type, a P(II) deletion mutant showed very little nif expression. This effect of P(II) on nif expression is apparently the result of a requirement of P(II) for NifA activation, whose activity is regulated by NH(4)(+) in R. rubrum. The modification of glutamine synthetase (GS) in these glnB mutants appears to be similar to that seen in wild type, suggesting that a paralog of P(II) might exist in R. rubrum and regulate the modification of GS. P(II) also appears to be involved in the regulation of DRAT activity, since an altered response to NH(4)(+) was found in a mutant expressing P(II)-Y51F. The adenylylation of GS plays no significant role in nif expression or the ADP-ribosylation of dinitrogenase reductase, since a mutant expressing GS-Y398F showed normal nitrogenase activity and normal modification of dinitrogenase reductase in response to NH(4)(+) and darkness treatments.
