Appendix E. Results from subsampling studies from the entire data set.

This appendix includes tables showing results from subsampling studies from the entire data set, as well as statistical test for the comparisons illustrated in Fig. 4 in the text.

TABLE E1: Number of 5000 randomly drawn subsets of the studies from the full data set for which the upper 95% confidence limit for the specified log response ratio effect size was less than zero (<0) or the lower 95% confidence limit was greater than zero (>0), under three criteria for non-independence of data from the same study (see text).
