Fig. 6From: Exosome microRNA signatures in patients with complex regional pain syndrome undergoing plasma exchangeChanges in plasma levels of IL-6 and TNF alpha in CRPS patients following plasma exchange (PE). Plasma levels of IL6 and TNFα were evaluated in plasma from 18 CRPS patients before and 2 weeks following PE. IL-6 was significantly lower following PE but TNFα was not. The significance was determined using student paired t-test (***p < 0.001)Back to article page
