I have tried to follow the examples in the forum on matching cases / controls but have been unsuccessful.
I have a large dataset of 21700, where 187 are cases. I have information on age, sex , state and cause of death for all the study population. I would like to match 1 case for 4 controls. I am drawing my controls from same population of the cases. I would like to match on sex, age (within 5 years range) , State of residence, and cause of death ( 3 categories) .
Can I match this in steps; first on sex, age (within 5 years range) , State of residence. Then from this first pool match them by cause of death?
How do I conduct this in STATA 9 the codes) and come up with cases and controls to answer my question of interest if the odds in my cases is higher than the controls
