Use with caution (coefficient of variation 16.6% to 33.3%). †Estimate suppressed due to small sample size. ‡If coefficient of variation of estimate exceeds 33%, estimate is indicated as being less than upper limit of 95% CI. The total number of people aged 40 to 75 years old recommended for statin use are 4.9 million, 95% CI 4.4 to 5.5 million, according to the Modified Framingham risk algorithm and CCS guidelines and 4.3 million, 95% CI 3.9 to 4.8 million, according to the US pooled risk algorithm and ACC-AHA guidelines.
