Comparison of clinicopathological characteristics and survival outcomes between gallbladder mucinous adenocarcinoma and gallbladder adenocarcinoma: A propensity score-matched study

Table 3 Outcomes after baseline factors adjustments

Outcomes	GBMAC, HR (95%CI)	P value
Cancer-specific mortality
Non-adjusted	1.13 (0.96-1.34)	0.15
PSM non-adjusted	0.96 (0.76-1.2)	0.7
PSM adjusted	1.00 (0.79-1.28)	0.98
Adjust I	1.11 (0.94-1.31)	0.23
Adjust II	0.93 (0.78-1.10)	0.39
Adjust III	1.14 (0.97-1.35)	0.12
Adjust IV	1.01 (0.85-1.20)	0.89
Overall mortality
Non-adjusted	1.13 (0.96-1.33)	0.13
PSM non-adjusted	0.98 (0.78-1.22)	0.83
PSM adjusted	1.02 (0.80-1.28)	0.9
Adjust I	1.10 (0.94-1.30)	0.22
Adjust II	0.94 (0.80-1.10)	0.44
Adjust III	1.15 (0.98-1.35)	0.08
Adjust IV	1.02 (0.87-1.20)	0.78

The propensity score matching (PSM) non-adjusted model adjusts for none. PSM adjusted model adjusts for age, sex, surgery, chemotherapy, histological grade, T stage, N stage, and M stage. Adjust I model adjusts for age, sex, race, and marital status. Adjust II model adjusts for the histological grade, American Joint Committee on Cancer stage, T stage, N stage, and M stage. Adjust III model adjusts for sex, age, T, N, and M stages. Adjust IV model adjusts for surgery, chemotherapy, and radiotherapy. GBMAC: Gallbladder mucinous adenocarcinoma; HR: Hazard ratio; PSM: Propensity score matching.
