	Number of days after perforation
Genotype	Day 9	Day 12	Day 15
WT	6/10 (60%)	9/10 (90%)	10/10 (100%)
tPA^−/−	11/18 (61%)	9/10 (90%)	10/10 (100%)
uPA^−/−	1/18 (6%)	6/10 (60%)	10/10 (100%)
P value	0.000912***	0.153355	N/A

The data are shown as the number of closed TM perforations with a continuous keratin layer in relation to the total number of TM perforations examined. The healing rate was calculated and is shown in brackets. *** P<0.001.
