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

Drug-resistant bacteria are rapidly becoming a significant problem across the globe. One element that factors into this crisis is the role played by bacterial biofilms in the recalcitrance of some infections to the effects of conventional antibiotics. Bacteria within a biofilm are highly tolerant of both antibiotic treatment and host immune responses. Biofilms are implicated in many chronic infections, including tuberculosis, in which they can act as bacterial reservoirs, requiring an arduous antibiotic regimen to eradicate the infection. A separate, compounding problem is that antibiotics once seen as last-resort drugs, such as the polymyxin colistin, are now seeing more frequent usage as resistance to front-line drugs in Gram-negative bacteria becomes more prevalent. The increased use of such antibiotics inevitably leads to an increased frequency of resistance. Drugs that inhibit biofilms and/or act as adjuvants to overcome resistance to existing antibiotics will potentially be an important component of future approaches to antibacterial treatment. We have previously demonstrated that analogues of the meridianin natural product family possess adjuvant and antibiofilm activities. In this study, we explore structural variation of the lead molecule from previous studies, and identify compounds showing both improved biofilm inhibition potency and synergy with colistin.
