1 Paper 209-29 Simplified Matched Case-control Sampling using PROC SURVEYSELECTR obby Diseker, Kaiser Permanente, Atlanta, GeorgiaABSTRACTE pidemiological studies sometimes are designed to compare two groups using one-to-one matching in orderto create a control group that is comparable to a case group on one or more risk factors. Producing equal-sized case and control samples that are Matched on multiple variables can present a challenge to anyprogrammer. using the PROC SURVEYSELECT procedure in SAS Version 8 software can facilitate thedevelopment of such Sampling programs by eliminating the need for macros. This procedure has the abilityto select samples within independent stratified subgroups. This paper presents a program that can be simplyadapted that will select a Matched sample of equal numbers of cases and controls when matching onmultiple variables using simple random Sampling without studies can be designed to eliminate potential confounders by using one-to-one matching tocompare two groups.
