Table 3 Survival analysis considering the primary outcome and ITT analysis for 24 months of follow-up

From: Survival rate of primary molar restorations is not influenced by hand mixed or encapsulated GIC: 24 months RCT

Trial groups Survival proportion % SE HR (95%CI) p
Survival analysis (primary outcome)
Hand-mixed group 60.9 0.04 1.00 0.626*
Encapsulated group 59.3 0.05 0.91 (0.61 to 1.35)
Trial groups Success Failure RR (95%CI) p
N (%) N (%)
Success at 24 months (intention to treat analysis)
Hand-mixed group 100 (62.1) 61 (37.8) 1.00 0.498**
Encapsulated group 99 (61.1) 63 (38.9) 0.88 (0.62 to 1.26)
