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 systemic symptoms of diphtheria are caused by the tox-encoded diphtheria toxin (DT) which is produced by toxigenic Corynebacterium spp. Besides the classical agent C. diphtheriae, the zoonotic pathogen C. ulcerans has increasingly been reported as an emerging pathogen for diphtheria. The reliable detection of toxigenic Corynebacterium spp. is of substantial importance for both diphtheria surveillance in the public health sector and the clinical workup of a patient with diphtherialike symptoms. Since the respective tox genes of C. diphtheriae and C. ulcerans differ from each other in both DNA and amino acid sequence, both tox genes should be covered by novel real-time PCR methods. We describe the development and validation of a LightCycler PCR assay which reliably recognizes tox genes from both C. diphtheriae and C. ulcerans and differentiates the respective target genes by fluorescence resonance energy transfer (FRET) hybridization probe melting curve analysis.
