I wonder if any of you know how to make a continuous blood pressure variable from two variables? I have continuous variables for systolic and diastolic pressure: systolic_bp and diastolic_bp. These are expressed by the following ratio: systolic over diastolic pressure (for instance 145/83). I want to create a continuous variable, bp, that looks like this (example):
| systolic_bp | diastolic_bp | bp |
| 180 | 95 | 180/95 |
| 140 | 90 | 140/90 |
| 137 | 75 | 137/75 |
| etc... |
Best regards,
Sigrid
