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

Optimal levels of ftsZ gene product are shown to be required for initiation of the cell division process in Mycobacterium tuberculosis. Here, we report that the ftsZ gene expression is sharply down-regulated during starvation and hypoxia, conditions that are believed to result in growth arrest, but is restored upon dilution of cultures into fresh oxygen-rich media. Primer extension analysis identified four transcriptional start sites, designated as P1, P2, P3 and P4 at nucleotide positions -43, -101, -263, and -787, respectively, in the immediate upstream flanking region of the ftsZ initiation codon. Promoter deletion and homologous recombination experiments revealed that ftsZ expression from the 101-bp region is sufficient for M. tuberculosis viability. All promoter strains had reduced FtsZ levels compared to wild-type, although the loss of P4 severely compromised FtsZ levels during both the active and stationary phases. We propose that ftsZ expression from all promoters is required for optimal intracellular FtsZ levels and that the activities of P4 and possibly other promoters are down-regulated during growth-arrest conditions.
