Follow-up ranged from 30 days to 11 years for ARCG and 30 days to 8 years for PPE. Meta-analysis revealed that PPE had higher pooled infection, framework exposure, and redo operation rate differences of 3.18% (95% confidence interval [CI]: \u22122.00, 8.36%), 6.97% (95% CI: 0.07, 13.86%), and 4.88% (95% CI: \u22123.45, 13.20%), respectively.
