Figure 9

Forest plot of fish assemblage effect sizes based on biomass data in the NTR and the PPA. Each row represents a paired NTR-PPA comparison. Italcomis Reef NTZ vs. MUZ was excluded from the sensitivity analysis due to habitat confounding effect. The vertical dotted line at $\overline{\mathit{\text{LnRR}}}$ = 0 represents equal fish density in the NTR and PPA; $\overline{\mathit{\text{LnRR}}}$ > 0 means more fish inside the NTR; $\overline{\mathit{\text{LnRR}}}$ < 0 means fewer fish in the NTR. The squares are the effect size for each MPA, the error bars are the 95% confidence interval for each MPA, whose values are given on the right hand side of the figure. Summary effect: the diamond represents the weighted mean calculated from the random effects meta-analysis, the width of the diamond is proportional to the estimation in the error of the mean and the horizontal dotted line is the prediction interval were 95% of true effects are predicted to lie.
