Randomisations per Day — Multicentre Trial Recruitment, 2025
Daily randomisations into a fictional multicentre trial as sites open through the year: 398 participants in 2025, 119 in the first half and 279 in the second, with no randomisation at weekends, on the eight English bank holidays or over the Christmas closure. The thickening of the grid from spring onward is site activation, not seasonality. Illustrative values.
