Estimates of the impact of unreamed vs reamed intramedullary nailing on reoperation

Comparison	Direct evidence OR (95% CI)	Direct evidence certainty in estimates	Indirect evidence OR (95% CI)	Indirect evidence certainty in estimates	Network OR (95% CI)	Network certainty in estimates
Unreamed compared with reamed	0.74 (0.45 – 1.24)	⊕⊕⊕Ο MODERATE	0.07 (0.01–0.46)	⊕⊕ΟΟ LOW	0.62 (0.37–1.03)	⊕⊕ΟΟ LOW

OR = odds ratio; direct, indirect, and network estimates of the effect of unreamed vs reamed intramedullary nailing on reoperation as reported in a network meta-analysis on management strategies for open tibial shaft fractures [7]. In this case, the estimate from direct evidence warrants higher certainty than the combined network estimate.
