Understanding the Implications of Non-Equal Slopes in Regression Analysis: A Case for Further Investigation.
Based on the code output, the null hypothesis that the slopes are equal cannot be rejected. The estimated intercept (-2120.98) and the coefficient of log(VE) (914.32) indicate a positive relationship between absVO2 and log(VE), which is consistent with your initial assumption. However, the interaction term groupHealthy:log(VE) (60.52) suggests that there may be some variation in the slope between groups Healthy and CAD. While this coefficient is not significant (p-value = 0.
