  • IQR, interquartile range.

  • The 4 waves were reported separately because the starting and end dates were different.

  • * Delay I was calculated based on Z score > 1.282, which corresponds to a one-tailed 90% confidence interval. Delay I is identified if the interval between activities (IBA) deviates from the practice's normal pattern of facilitation activities.

  • Delay II was calculated based on Z-score > 1.645, which corresponds to a one-tailed 95% confidence interval. Delay II captures a larger deviation from the normal pattern compared to Delay I. Delay I is more sensitive to detecting delays than Delay II and could capture more instances of infrequent facilitation activities.
