Multivariable adjusted (Model 2) cosine periodic model estimates for log HF over the clock time at the population mean and one SD above the mean in log HOMA-IR. Abbreviations: Â, amplitude; HF, high frequency power; HOMA-IR, homeostasis model assessment of insulin resistance; log, logarithm; M, mean; SD, standard deviation; θ, acrophrase time.
