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.

Abstract

objectiveTo compare liraglutide versus common antihyperglycemic treatments in reducing hemoglobin A1c (A1C) values across multiple levels of baseline glycemic control and in reaching glycemic targets.

methodsPooled patient data from 7 phase 3, multinational, randomized controlled trials in patients with type 2 diabetes were stratified by baseline A1C values into 5 categories: ≤7.5%, >7.5% to 8.0%, >8.0% to 8.5%, >8.5% to 9.0%, and y9.0%. The changes in A1C from baseline to week 26 of treatment and patient proportions reaching A1C targets of <7.0% and ≤6.5% were compared between liraglutide (1.8 mg daily) and sitagliptin, glimepiride, rosiglit-azone, exenatide, and insulin glargine across all baseline A1C categories.

resultsIrrespective of treatment, reductions in A1C levels were generally greater in groups with higher baseline A1C values. After 26 weeks of treatment, liraglutide produced the greatest reductions in A1C values across all baseline categories, ranging from 0.7% to 1.8% (baseline A1C categories ≤7.5% to >9.0%, respectively), followed by insulin glargine (0.3% to 1.5%) and then by glimepiride (0.4% to 1.3%). Generally, larger percentages of patients achieved the A1C target of ≤6.5% with liraglutide therapy across all baseline categories (from 62% of patients with A1C values ≤7.5% to 10% of patients with A1C values >9.0%) in comparison with other treatments (ranging from 49% to 0% of patients, respectively). Similarly, greater proportions of patients also reached the A1C target of <7.0% with liraglutide therapy across all baseline categories (from 83% of patients with A1C values ≤7.5% to 25% of patients with A1C values >9.0%) versus comparators (from 74% to 5% of patients, respectively).

conclusionAcross a wide spectrum of baseline A1C categories, liraglutide is an efficacious treatment option for patients with type 2 diabetes.
