CCL2 levels at radiotherapy end could be modelled using linear regression including the following variables: baseline CCL2 (coefficient = 1.15, p = 0.0001), age (coefficient = −3.26, p = 0.004), abdominal surgery (coefficient = 23.3, p = 0.09), hypertension (coefficient = 29.6, p = 0.02), and use of anticoagulants (coefficient = 41.0, p = 0.05) and multiple correlation coefficient = 0.89 (see plot). Here, CCL2 is linked to Hypertension.
