From: An examination of sleep spindle metrics in the Sleep Heart Health Study: superiority of automated spindle detection over total sigma power in assessing age-related spindle decline

Fig. 3

A Population NREM2 sigma coherence as a function of age. Note the drop in coherence over time. B Population spindle sigma coherence as a function of age shows a steeper slope. C Mean NREM2 sigma coherence at the time of the first test is significantly (p < 0.001) higher than at the time of repeat testing a minimum of 3 years later. D Same as C but using spindle sigma coherence
