Figure 4

Lomb-Scargle periodogram for patient no. 3 in Figure 3. The significance levels shown are approximate. This patient has three significant peaks in the periodogram with periods 1/𝑓 equal to 85 days, one day, and 12 hours and respective significance levels 𝑃=.018, 𝑃=.0088, and 𝑃=2.6⋅10⁻⁵. The periodogram is plotted up to four times the average Nyquist frequency and with an oversampling factor of five.
