From: No increased drought-related mortality after thinning: a meta-analysis
Forest plot of the subgroup analysis of Koeppen Climate Zones with effect size of pre-drought periods (blue) and drought periods (orange). Effect size is the risk ratio; the x-axis is in log scale; the lower the effect size, the lower is the mortality rate in thinned stands relative to their control. There are 2 experiments in the warm/arid zone, 3 in the Temperate zone and 27 in the Continental zone
