Key clinical point: Higher intake of coffee and decaffeinated coffee was associated with a higher risk of developing rheumatoid arthritis (RA).
Major finding: Each additional cup of coffee and decaffeinated coffee consumed per day increased the risk of developing RA by 6% (relative risk [RR] 1.06; 95% CI 1.02-1.10) and 11% (RR 1.11; 95% CI 1.05-1.18), respectively. However, no such association was observed between consumption of caffeinated coffee, caffeine, or tea and risk for RA.
Study details: This was a dose-response meta-analysis of five prospective cohort studies involving 266,985 participants.
Disclosures: No information on funding was reported. The authors declared no potential conflicts of interest.
