Seasonal and Weekly Patterns of Korean Adolescents’ Web Search Activity on Insomnia: Retrospective Study

The seasonal trend across the months in the year was examined in the slow fluctuation component (low pass–filtered data), and the weekly trend was analyzed using the fast fluctuation component (high pass–filtered data). We conducted data analysis using MATLAB R2023a (Math Works). We performed 2-way ANOVA to check for a significant group×month interaction in the seasonal trend and a group×day interaction in the weekly trend.

With our study design, this cannot be completely excluded.
