Table 3. Outcomes by Protocol Duration (n = 286 surgeries; for surgeries that required revisions, the days from initial surgery until healed post-revision is used for duration. Patients who never achieved remobilization are excluded from some analyses – see text).

	4-week	6-week	Difference (6 vs. 4 week)	p
Days from surgery to 2 h sitting – each subject included only once (random)	54 median (IQR = 54)(n = 109)	60 median (IQR = 37)(n = 75)	+6d	0.041 (Mann–Whitney U test)
Days from surgery to 2 h sitting – subject included more than once	54 median (IQR = 46)(n = 167)	59 median (IQR = 28)(n = 113)	+5 d	0.019 (Mann–Whitney U test)
Days from surgery to discharge –	70 median (IQR = 60)(n = 167)	78 median (IQR = 44)(n = 113)	+8 d	0.019 (Mann–Whitney U Test).
Dehiscence rate	88/171 (51.5%)	66/115 (57.4%)	+5.9%	0.34 (Fisher’s Exact Test)
Revision surgery performed during hospitalization	24/171 (14.0%)	10/115 (8.7%)	–5.3%	0.20 (Fisher’s Exact Test)
Rate of recurrence during first year post-surgery (excluding deceased, lost to follow-up, or never healed)	46/157 (29.3%)	22/111 (19.8%)	–9.5%	0.089 (Fisher’s Exact Test)
