↵a Pearson’s χ2 test did not demonstrated a statistically significant association between stage and CXR result, χ2 (1, N = 880) 1.67, P = 0.196. The result is not significant at P<0.05, 1 degree of freedom. Patients for whom stage was unknown are not included in order to maintain anonymity. CXR = chest X-ray.
