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

Mycobacterium tuberculosis Rv0164 has previously been identified as a human T-cell antigen that induces significant production of IFN-γ in human peripheral blood mononuclear cells. M. smegmatis MSMEG_0129 shares 59% sequence identity with Rv0164. Based on sequence alignment, both proteins are predicted to be members of the cyclase/dehydrase family, which is part of a large group of enzymes referred to as type II polyketide synthases (PKSs). In biosynthetic pathways mediated by type II PKSs, cyclases catalyze the conversion of linear poly-β-ketones to cyclized intermediates. To date, no mycobacterial type II PKSs have been reported. Here, the goal is to determine whether these proteins adopt similar folds to reported cyclase structures, and to this end MSMEG_0129 was cloned, expressed, purified and crystallized. An X-ray diffraction data set was collected to 1.95 Å resolution from a crystal belonging to space group P6
