Synthesis in BMJ open, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT02887677 (A Study of the Effects of Dapagliflozin on Ambulatory Aortic Pressure, Arterial Stiffness and Urine Albumin Excretion in Patients With Type 2 Diabetes), which is not on this map. Cited by 31 papers, 3 of them syntheses that pooled it.

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

objectivesThis meta-analysis aimed to evaluate whether dapagliflozin is synergistic with other antidiabetic drugs without body weight gain.

settingRandomised controlled trial (RCT) reports were retrieved from PubMed, Cochrane Library, EMBASE, ClinicalTrials.gov, Google Scholar and Google. Eligible RCTs were selected according to the criteria (including types of participants, intervention, outcomes) and assessed by the Cochrane risk of bias tool and GRADEpro software for evidential quality. Meta-analysis on the eligible RCTs was performed with the random effects model. The RCTs of low-quality and interim stages were excluded for further sensitivity analysis. Meta-regression was conducted on the follow-up durations. Publication bias was evaluated with funnel plots and the Egger's regression test and adjusted using the trim-and-fill procedure. Heterogeneity was assessed with the I(2) statistics.

participantsAdult patients with type 2 diabetes mellitus (T2DM).

interventionsDapagliflozin combined with conventional antidiabetic drugs. PRIMARY AND SECONDARY OUTCOME MEASURES: Glycaemic level (measured by glycosylated haemoglobin (HbA1c) and fasting plasma glucose (FPG)) and body weight.

results12 RCTs were eligible for quantitative synthesis and meta-analysis. The overall effect size of HbA1c calculated from mean difference was -0.52% (Z=-13.56, p<0.001) with 95% CI (-0.60 to -0.45). The effect size of FPG was -1.13 mmol/L (Z=-11.12, p<0.001) with 95% CI (-1.33 to -0.93). The effect size of body weight was -2.10 kg (Z=-18.77, p<0.001) with 95% CI (-2.32 to -1.88). Exclusions of low quality and interim RCTs changed the overall mean differences respectively to -0.56%, -1.11 mmol/L, 2.23 kg and -0.50%, -1.08 mmol/L, -2.08 kg. The sensitivity analysis indicated good robustness of the meta-analysis on HbA1c, FPG and body weight.

conclusionsThe meta-analysis showed that dapagliflozin as an add-on drug to conventional antidiabetic drugs improved the glycaemic control in T2DM participants without significant body weight gain. TRIAL REGISTRATION NUMBER: CRD42013005034.
