RELRISK (METHOD=FMSCORE)

[sarahsasuser]

Hi All,

I want to calculate the relative risk and 95%CI using the FM Score in proc freq. I'm interested in comparing the the WAld CI and the FM CI. However, when I add it to my code I get this error:

130  proc freq data=Data.xxx;

131     132      table any_dia*status/ EXACT RELRISK (METHOD=FMscore) ;

ERROR 22-322: Syntax error, expecting one of the following: PDIFF, RDIFF, RISKDIFF, RISKDIFFC.

ERROR 76-322: Syntax error, statement will be ignored.

133  run;

It looks like I should use the riskdiff to use this option. However, I do not want the risk difference and  this documentation says I can get the FMScore from relrisk.

Base SAS(R) 9.3 Procedures Guide: Statistical Procedures

I'm using version 9.3.

Any ideas?

Switch it to the exact statement and note that you can only do relrisk calculations for 2x2 tables.

proc freq data=Data.xxx;

table any_dia*status;

EXACT RELRISK (METHOD=FMscore) ;

run;
