From: Characterizing the time of day and year of falls in people with probable Parkinson’s disease

Fall time of day across those with and without probable PD (left) and gender (right). Chi-square tests indicate statistically significant effects of both PD and gender on frequency of falls throughout the day. Of note, morning, forenoon, and evening are 3 h windows, afternoon is a 6 h window, and night is an 8 h window.
