Fig. 2From: The association between diabetes and dermal microvascular dysfunction non-invasively assessed by laser Doppler with local thermal hyperemia: a systematic review with meta-analysis Forest plot of pooled overall effect of microvascular function in diabetic patients versus control subjects based on a random effects model.
