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

The arginine deiminase (AD) system (ADS) is one of two major ammonia-generating pathways in the oral cavity that play important roles in oral biofilm pH homeostasis and oral biofilm ecology. To initiate a study of the Streptococcus gordonii ADS, the ADS gene cluster was isolated from subgenomic DNA libraries of S. gordonii DL1 by using an arcB-specific probe. Nucleotide sequence analysis revealed six open reading frames (ORFs) that were arranged contiguously; the first five ORFs were transcribed in the same direction, as an apparent operon, and the sixth was transcribed in the opposite direction. The ORFs were found to share significant homologies and to correspond closely in molecular mass to previously characterized arc genes; thus, they were designated arcA (AD), arcB (ornithine carbamyltransferase), arcC (carbamate kinase), arcD (arginine-ornithine antiporter), arcT (dipeptidase), and arcR (regulator). A putative sigma(70) promoter (ParcA [TTGTGT-N(19)-TAGAAT]) was mapped 5' to arcA by primer extension, and the expression of ParcA was shown to be inducible by arginine and repressible by glucose, in agreement with AD specific activities measured in the wild-type strain. To investigate the function of ArcR in the differential expression of the arc operon, arcR was insertionally inactivated by a KM resistance marker flanked by T4 transcription/translation termination signals, and the expression of ParcA was monitored by primer extension in the wild-type and ArcR-deficient strains. Lower levels of arcA expression, as well as lower levels of AD activity, were consistently observed in the ArcR-deficient strain compared to wild-type cells, regardless of the growth conditions. Thus, ArcR is a transcriptional activator that is required for induction and optimal expression of the S. gordonii ADS gene cluster.
