TABLE 3.

Multivariate Cox proportional hazard model for polyp recurrence within 4 years comparing UT and NP ECP

Factor	Hazard ratio	95% CI	p
UT ECP (ng/mg total protein)
≥290	2.80	1.02–7.65	0.045^*
<290	Reference
Postoperative nasal steroid spray use	0.55	0.23–1.32	0.179
Postoperative oral steroid use	1.42	0.57–3.55	0.453

p < 0.05.

CI = confidence interval; ECP = eosinophil cationic protein; NP = nasal polyp; UT = uncinate tissue.
