CCL2 and hypertensive disorder: Amultiple linear regression analysis, adjusted for age, presence of LVH, and RH,revealed that only beta-blockers were independently associated with MCP-1 levels(beta coefficient = 55, standard error [SE] = 20, p < 0.01).Nevertheless, this possible interference might not have affected the outcome of ourstudy, since RH subjects had similar MCP-1 levels as HTN ones, despite the use of agreater proportion of beta-blocker agents.
