1. Subgroup analysis of associations between daily tea consumption and risk of ischaemic heart disease (IHD) according to potential baseline risk factors.
Subgroup analysis of associations between daily tea consumption and risk of ischaemic heart disease (IHD) according to potential baseline risk factors. HRs for IHD or major coronary events (MCEs) are for comparison of daily tea consumer with participants who never consumed tea during the past 12 months. Risk estimates for other categories of tea consumption are shown in online supplementary table S3. Solid dots represent point estimates, and horizontal lines represent 95% CIs. An HR of <1 means daily tea consumption was associated with a reduction in the risk of the outcome of interest. The tests for interaction were performed using likelihood ratio tests, which involved comparing models with and without cross-product terms between the baseline stratifying variable and tea consumption as an ordinal variable. BMI, body mass index; MET, metabolic equivalent task.
