Comparison of the micro- and macro-vascular effects of glimepiride and gliclazide in metformin-treated patients with Type 2 diabetes: a double-blind, crossover study.
Trial report in British journal of clinical pharmacology, 2003. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
aimsTo compare the metabolic and vascular effects of two sulphonylureas (SU), gliclazide (specific for the pancreatic [SUR1] receptor) and glimepiride (a nonspecific agent that also binds to vascular and cardiac [SUR2] receptors), during chronic administration in metformin-treated patients with Type 2 diabetes (T2DM).
methodsA randomized, double-blind, crossover study of gliclazide 80 mg BID and glimepiride 2 mg OD, each for 4 weeks as add-on therapy to metformin, with a 4-week washout period. Patients attended four study mornings after first dose and 4 weeks' SU treatment for measurements of arterial distensibility (Ax), pressor responsiveness to i.v. angiotensin II (ANGII), and cutaneous microvascular vasodilator responses to iontophoresis of acetylcholine (ACh) and sodium nitroprusside (SNP).
resultsGlycaemic responses were similar (e.g. serum fructosamine was 315 vs 329 micro mol l-1 after 4 weeks), and there was no change in augmentation index during treatment with either SU (9.1 vs 9.8 mmHg after 4 weeks [95% confidence interval -8.1, 10.5]). Similarly, there were no differences between treatments in pressor responsiveness (e.g. PD10[dose of agonist required to increase mean BP by 10 mmHg] for ANGII was 1.37 vs 1.68 ng kg-1 min-1[-4.3, 6.9]) or cutaneous microvascular vasodilator responses (peak ACh response 68 +/- 36 vs 63 +/- 34 perfusion units [-82.7, 79.1]).
conclusionsThere is no evidence that SUR1-specific and nonspecific SUs have differential effects on arterial distensibility, endothelial function or vasodilator mechanisms in metformin-treated patients with T2DM.
