title: Circannual and/or transannual variations in growth hormone and beyond--call for long data series.
abstract: A meta-analysis of growth hormone data showing similar double amplitudes of 36 and 34% of the mean from the fit of cosine curves with periods of 1.3 and 1.0 year, respectively, suggests the desirability of analyzing available time series on variables of interest in biomedicine, to explore heretofore unknown longer-than-yearly cycles that may interact (beat) with yearly ones.
