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

BACKGROUND AND

objectiveMetformin is a first-line treatment for patients with diabetes. Recent animal studies indicated that metformin can reduce airway inflammation. However, it remains unclear whether the use of metformin can help patients maintain asthma control. The purpose of this study was to evaluate the association between the use of metformin and asthma-related outcomes, which include asthma-related hospitalization, asthma-related emergency room visits and asthma exacerbation, among patients with concurrent asthma and diabetes.

methodsWe conducted an 11-year (2001-2011) retrospective cohort study using the Taiwan National Health Insurance Research Database. Patients with concurrent asthma and diabetes were included. The date of the first observed prescription of metformin was defined as the index date. For each metformin user, two matched metformin non-users of the same age and gender were randomly selected. Patients were followed for 3 years to measure the occurrence of asthma-related outcomes. Multivariable logistic regression models were used to assess the association between metformin use and asthma-related outcomes.

resultsOf 1332 patients with concurrent asthma and diabetes, 444 (33.3%) were metformin users. Compared with non-users, metformin users had a lower risk of asthma-related hospitalization (OR = 0.21, 95% CI: 0.07-0.63) and asthma exacerbation (OR = 0.39, 95% CI: 0.19-0.79).

conclusionThe risk of asthma-related outcomes was lower for metformin users than non-users. Health-care providers should consider metformin as a treatment strategy for patients with concurrent asthma and diabetes.
