Eligible patients
We found a total of 19,681 patients with RA in the Longitudinal Health Insurance Database 2005 (LHID 2005). Of those, 15,097 patients had cardiovascular diagnostic coding. Patients who did not have associated cardiovascular coding were not listed in Table 2 for analysis. Among these patients, 4,810 patients were diagnosed with RA, nine of which were treated with biologic agents. Similarly, 13,384 patients had metabolic diagnostic coding. Patients that did not have associated metabolic coding were not listed in Table 2 for analysis. Among these patients, 5,680 patients were diagnosed with RA, nine of which were treated with biologic agents.
In the LHID 2005 database, 18,114 patients had rheumatologic or orthopedic diagnostic coding. Patients who did not have associated rheumatologic or orthopedic coding were not listed in Table 2 for analysis. Among these patients, 2,269 patients were diagnosed with RA, seven of which were treated with biologic agents. Again, in the LHID 2005 database, 19,681 patients had oncologic diagnostic coding. Patients that did not have associated oncologic coding were not listed in Table 2 for analysis. Among these patients, 3,148 patients were diagnosed with RA, 23 of which were treated with biologic agents. Of the 18,944 patients with infectious related diagnostic coding, 1,092 patients were diagnosed with RA, and seven of those were treated with biologic agents. Finally, 13,047 had miscellaneous diagnostic coding related to RA. Among these patients, 4,996 patients were diagnosed with RA, seven of which were treated with biologic agents.
