The Hartung-Knapp-Sidik-Jonkman method for random effects meta-analysis is straightforward and considerably outperforms the standard DerSimonian-Laird method

Table 6 R output for second example (Hartung-Knapp-Sidik-Jonkman method)

	Estimate (HR)	SE	t-value	p-value	CI.LB	CI.UB
R output	−0.1458	0.0470	−3.1031	0.0127	−0.2521	−0.0395
After back-transformation	0.8643				0.7772	0.9613

Relevant part from output from R package metafor. HR: hazard ratio; SE: standard error; CI.LB: lower bound of 95% confidence interval; CI.UB: upper bound of 95% confidence interval.
