* With focus on transyears with periods longer than 1.0 year.
¹International Classification of Disease (ICD10) Code I46.1, excluding MI and sudden death of unknown or unspecified cause (except before 1999). T: Length of data series (y = years); Δt: sampling interval (d = day, m = month); N: number of data (including 0s). Period and 95% confidence interval (CI) estimated by nonlinear least squares. In longer (10-y) series, a neartransyear (cycle with a period between 1.0 and 1.2 y) is detected for MIs in addition to a fartransyear. Brevity of series and lack of ordering statistical significance qualify results from Hong Kong. Note that transyears are found in 3 of 6 locations (P < 0.05 by linear least squares) with a relative amplitude >12 (% of MESOR).
²From linear least squares analysis, not corrected for multiple testing. Amplitude expressed in N/day.[62]
