CCL2 and breast carcinoma: MCP‐1 and lymph node involvement maintain the highest HRs across univariate, age‐adjusted and multivariable‐adjusted models for distant relapse (MCP‐1: adjusted HR = 1.66; 95% CI = 0.77–3.61, lymph node involvement: adjusted HR = 4.91; 95% CI = 2.09–11.56) (Table 2) and breast cancer‐related death with distant relapse (MCP‐1: adjusted HR = 2.21; 95% CI = 0.92–5.31, lymph node involvement: adjusted HR = 5.94; 95% CI = 2.21–15.95) (Table 3).
