Table 1 Patient demographics and baseline clinical status

Patient demographics (n = 10)
Age, mean (range)	73 (67-85)
Sex, male, No. (%)	10 (100)
Race, white, No. (%)	10 (100)
CRP Patients (n = 8)
Prior treatment	RFA-naïve, n = 5	Previously-treated, n = 3
Prior RFA sessions, mean (range)	0 (0)	2 (1-3)	P value
Baseline RTD score, mean ± SD	2 ± 0.7	0.3 ± 0.6	0.007
Baseline Hgb, g/dL, mean ± SD	13.7 ± 1.8	12 ± 0.8	0.23

Hgb: Hemoglobin concentration; SD: Standard deviation; CRP: Chronic radiation proctopathy; RFA: Radiofrequency ablation; RTD: Rectal telangiectasia density.
