Table 2. Model-averaged coefficients and their unconditional 95% confidence intervals.
Model-averaged coefficients were estimated by multimodel inference following model selection (see Table 1) and computed with standardized explanatory variables (zero mean and unit variance). Parameters for which their confidence interval does not overlap zero are shown in bold text. The number of sites (S) and of workers (W) used in analyses are shown where applicable.
