Evaluating Anti-Infective Drugs in the Resistant Pathogen Setting: Can we Use External Controls?
Article in Statistical communications in infectious diseases, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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.
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
Decreased efficacy of antibiotics due to resistant pathogens has created a need for the development of more effective medical interventions. Despite the increasing prevalence of pathogens resistant to one or more drugs, identifying and enrolling participants into clinical trials that evaluate new interventions for the treatment of some diseases can be challenging given the low prevalence of disease in which there are no effective treatments. Thus researchers might be tempted to consider externally-controlled trials that may allow for a reduction of the necessary number of prospectively-identified trial participants, thus easing recruitment burden and resulting in more timely trial completion relative to randomized controlled trials. We discuss advantages and disadvantages in externally controlled trials and review requirements for a valid externally-controlled trial. As ECTs are subject to the bias of observational studies, the criteria for a valid ECT should be carefully evaluated before these designs are implemented. Given considerable variation in study results in the resistant pathogen setting, the lack of information on important patient characteristics that may confound estimates of treatment effects, as well as the improvements in medical practice and evolving antibiotic resistance, the use of ECTs in the resistant pathogen setting, is not recommended. ECTs should be should be limited to specific situations where superiority of the effect of the new intervention is dramatic, the usual course of the disease highly predictable, the endpoints are objective (e.g., all-cause mortality) and the impact of baseline and treatment variables on outcomes is well characterized. Given that the resistant pathogen setting does not satisfy these criteria, we conclude that that randomized clinical trials are needed to evaluate new treatments for resistant pathogens. Innovative approaches to trial design that may ease recruitment burden while evaluating the benefits and harms of new treatments are being developed and utilized.
