Researchers enroll 100 cases of lung cancer in a study, and 35% are White and 52% are male. Controls are selected so that 35% of the control group participants are White and 50% of control group participants are male. This is an example of: Researchers enroll 100 cases of lung cancer in a study, and 35% are White and 52% are male. Controls are selected so that 35% of the control group participants are White and 50% of control group participants are male. This is an example of: Individual matching Randomization Group frequency matching
