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 expression of phenotypic drug resistance or drug tolerance serves as a strategy for Mycobacterium tuberculosis to survive in vivo antimicrobial drug treatment; however, the mechanisms are poorly understood. Progress toward a more in depth understanding of in vivo drug tolerance and the discovery of new therapeutic strategies designed specifically to treat drug-tolerant M. tuberculosis are hampered by the lack of appropriate in vitro assays. A library of 2-aminoimidazole-based small molecules combined with the antituberculosis drug isoniazid was screened against M. tuberculosis expressing in vitro drug tolerance as microbial communities attached to an extracellular matrix derived from lysed leukocytes. Based on the ability of nine of ten 2-aminoimidazole compounds to inhibit Mycobacterium smegmatis biofilm formation and three of ten molecules capable of dispersing established biofilms, two active candidates and one inactive control were tested against drug-tolerant M. tuberculosis. The two active compounds restored isoniazid susceptibility as well as reduced the in vitro minimum inhibitory concentrations of isoniazid in a dose-dependent manner. The dispersion of drug-tolerant M. tuberculosis with 2-aminoimidazole-based small molecules as an adjunct to antimicrobial treatment has the potential to be an effective antituberculosis treatment strategy designed specifically to eradicate drug-tolerant M. tuberculosis.
