Consolidation chemotherapy with capecitabine after neoadjuvant chemoradiotherapy in high-risk patients with locally advanced rectal cancer: Propensity score study

Table 4 The complete response rate and univariate regression of consolidation chemotherapy in the original samples before matching, after propensity score match and inverse probability of treatment weighting in the two groups

	CR			Univariate regression
	non-CC group, n (%)	CC group, n (%)	P value	OR (95%CI)	P value
Original samples	21 (16.3)	33 (24.3)	0.107	1.648 (0.895-3.033)	0.109
PSM	17 (16.2)	29 (27.6)	0.045	1.975 (1.008-3.871)	0.047
IPTW	21 (16.3)	35 (25.9)	0.045	1.185 (1.008-3.395)	0.047

CR: Complete response; PSM: Propensity score match; IPTW: Inverse probability of treatment weighting; CC: Consolidation chemotherapy; OR: Odds rate; CI: Confident interval.
