Table 2 Pooled risk ratios, characterising the ratio of mortality in thinned and unthinned stands from the pre-drought period to drought period, each consisting of the same 32 experiments. Drought-periods were selected with SPEI3Summer as described above. Between-study heterogeneity I2 quantifies how much of the variance cannot be explained by the sampling error
