Cardiovascular Mortality of Oral Antidiabetic Drugs Approved Before and After the 2008 US FDA Guidance for Industry: A Systemic Review and Meta-Analysis.

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
backgroundBoth diabetes and antidiabetic drugs (ADDs) increase the risk for cardiovascular (CV) diseases. Due to the increasing concern about CV safety associated with ADDs, the US FDA revised regulatory guidelines in 2008 to include CV safety as an endpoint.
objectiveThe objective of the current study was to conduct a systematic review with meta-analysis to compare CV mortality of oral ADDs approved before and after the FDA's 2008 guidance.
methodsThree electronic databases (PubMed, Scopus, and the Clinical Trial Registry) were searched to retrieve studies published up to 24 February 2017. Randomized clinical trials were included in this study if they (1) were published in the English language; (2) included adults with type 2 diabetes mellitus with or without CV risk factors, who were taking at least one oral antidiabetic drug; and (3) had at least one study outcome as CV mortality. Meta-analysis was performed using a random-effects model. Small-study effects were accessed using funnel plot symmetry. The primary outcome was CV mortality.
resultsWe found that there was no significant increase in CV mortality for drugs approved before and after 2008. The overall odds ratio (OR) and the upper bound of the two-sided 95% confidence interval (CI) for all drugs approved after 2008 (OR 0.74, 95% CI 0.52-1.07) were lower than the overall OR for all drugs approved before 2008 (OR 1.03, 95% CI 0.89-1.19). In addition, the upper bounds of the two-sided 95% CI for both groups of drugs before and after 2008 were below 1.3. Empagliflozin, which was approved after the guidance, was significantly associated with a reduction in CV mortality.
conclusionThe 2008 FDA guidance appears to have a positive impact on CV risk assessment of recently marketed drugs for the management of diabetes.
