The heatmap titled “Weekly Response Concentration per Participant” is displayed at the top center. The horizontal axis at the bottom is labeled “Week” and shows date markings from 2022-08-01 at the far left to 2024-01-15 at the far right, with intervals such as 2022-08-15, 2022-08-29, 2022-09-12, 2022-09-26, 2022-10-10, 2022-10-24, 2022-11-07, 2022-11-21, 2022-12-05, 2022-12-19, 2023-01-02, 2023-01-16, 2023-01-30, 2023-02-13, 2023-02-27, 2023-03-13, 2023-03-27, 2023-04-10, 2023-04-24, 2023-05-08, 2023-05-22, 2023-06-05, 2023-06-19, 2023-07-03, 2023-07-17, 2023-07-31, 2023-08-14, 2023-08-28, 2023-09-11, 2023-09-25, 2023-10-09, 2023-10-23, 2023-11-06, 2023-11-20, 2023-12-04, 2023-12-18, and 2024-01-01. The vertical axis on the left is labeled “Participant” and lists participant I D s from top to bottom: 1126, 1233, 1376, 1437, 1513, 1533, 1540, 1615, 1704, 1760, 1822, 1846, 1890, 2007, 2011, 2014, 2092, 2227, 2260, 2271, 2370, 2392, 2411, 2462, 2485, 2499, 2674, 2814, 3109, 3117, 3133, and 3277. The heatmap consists of rectangular cells representing the number of responses each participant gave per week, shaded in varying intensities of blue. Most cells are very light, indicating few or no responses. Darker blue clusters appear notably for participants 2392, 2411, and 3109, with the darkest shades between late 2022 and mid-2023. A vertical color scale appears on the right, labeled “Number of Responses,” ranging from 0 in white to 9 in dark blue with an interval of 1.Weekly participant response concentration throughout the study period.
