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. 5

For each sample size, 100,000 clinical trials were simulated by randomly subsampling patients and performing a t-test to try to detect a change in sigma coherence between baseline and follow-up recordings. Calculating sigma coherence just for spindles instead of all NREM2 consistently resulted in a higher power
