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

introductionCardiovascular morbidity and mortality is a major and still unresolved threat to patients with reduced glucose tolerance and Type 2 diabetes mellitus. In epidemiological studies, in non-diabetic subjects, post-prandial glycaemia is positively associated with the risk of diabetes, hypertension and cardiovascular events. If this epidemiological association is causal, Acarbose, which reduces post-prandial blood glucose concentrations, should result in a decrease in the risk of these events. The STOP-NIDDM trial investigated whether Acarbose reduces the risk of diabetes, hypertension and cardiovascular events. Consequently, the validity of the results of this trial is of major importance for future treatment in non-diabetic and diabetic patients.

methodsWe searched various databases and the Internet for publications of the design and the results of the STOP-NIDDM trial. A systematic review of these publications was done with respect to information about potential sources of bias and contradictory information in the articles.

resultsWe found several serious flaws in the STOP-NIDDM study, especially selection bias, inadequate blinding, bias in data analysis and reporting, and potential sponsoring bias.

conclusionsThe validity of the results of the STOP-NIDDM trial is seriously flawed. The clinical benefit of Acarbose and of the reduction of post-prandial glycaemia is unproven.
