Example output

Loading 'meta' package (version 4.8-4).
Type 'help(meta)' for a brief overview.
Number of studies combined: k = 70

                         RR           95%-CI     z  p-value
Fixed effect model   0.7728 [0.7342; 0.8135] -9.84 < 0.0001
Random effects model 0.7667 [0.7046; 0.8342] -6.17 < 0.0001

Quantifying heterogeneity:
 tau^2 = 0.0125; H = 1.10 [1.00; 1.28]; I^2 = 17.2% [0.0%; 39.1%]

Test of heterogeneity:
     Q d.f.  p-value
 83.33   69   0.1150

Details on meta-analytical method:
- Mantel-Haenszel method
- DerSimonian-Laird estimator for tau^2
- Continuity correction of 0.5 in studies with zero cell frequencies
