From: No increased drought-related mortality after thinning: a meta-analysis

Meta-regression of risk ratio and thinning intensity measured as ratio of stand density index in thinned and control stands in the inventory period before drought, values below 1 indicate a lower mortality rate in thinned treatments, the intercept is weakly significant (p < 0.05), the slope not. The size of the dot indicates the weight calculated from the variance of the respective experiment
