- Column (2) shows the regression of symptom score upon age after taking time since diagnosis into account, and column (3) shows the regression of symptom score upon time since diagnosis after taking age into account. The effects in columns (2) and (3) are therefore statistically independent. Regression coefficients are shown as the 'b' (unstandardised) coefficients, along with their standard error (SE) and significance levels (p). Entries in bold have p < .1.
