I am doing a study on the effects of bad blood sugar control on patients. BMI, age, type of diabetes (Type 1 and 2 or gestational diabetes) are all variables. Outcomes include C section, early labour etc. A reviewer told me
Comparisons should be adjusted to maternal age and baseline BMI.
How does one do this with an online calculator? I have been doing my calculations only with online calculators and have never ventured to use SPSS. Can anyone advise me?
