aWeighted totals were calculated by assigning dressing stability observations by the following values:
no separation, 1 ; slight separation, 2 ; clear separation, 4;
then dividing the result by the total count of samples (i.e., 36 for all days, and 12 for day 14).
Scores had a possible range of 1.0-4.0, with 1 being the optimum score
