Fisher’s exact test.

Cochran-Armitage test for trend.

Day is between 7:00 am to 11:00 pm. Weekday is Monday, starting from 7:00 am until Friday 11:00 pm. Weekend is after Friday 11 pm until Monday at 7:00 am.

⁴

For the most recent month prior to the current month in which a minimum of 48 simulations were conducted in the unit.

⁵

Wilcoxon rank-sum test.

Percentages are based on row totals.
