Summary of the weekday intervention.

Separate sections show Female patients (top), Male patients (middle), and All patients (bottom). For each section, the first row (Before) shows the distribution of appointments across weekdays Monday to Friday for the 12 months before the intervention. The second row (After) shows the same distribution for the 12 months after the intervention. The third row (Change [%]) shows the Before–After differences as number of appointments and percentages. After the intervention, appointments were loaded onto higher-attendance days. This change was more pronounced for female patients than for male patients.
