Proton pump inhibitors and all-cause mortality risk among cancer patients

Table 3 Hazard ratios (95%CIs) for all-cause mortality between new users of proton pump inhibitors compared to histamine 2 receptor antagonists in a secondary analysis

Outcome	PPI-users (n = 44834)	H2RA-users (n = 44834)	HR (95%CI)
At 1-year	8393	7980	1.51 (1.41-1.69)
At 2-years	12950	11989	1.16 (1.04-1.39)
Overall outcome during follow-up	18304	17146	1.17 (1.05-2.16)

PPI: Proton pump inhibitor; HR: Hazard ratio; H2RA: Histamine2 receptor antagonist.
