Table 3 Summary of the weighted simple random-effects regression models for each of the four moderator variables on fish assemblage biomass effect size

From: Evaluating the biological effectiveness of fully and partially protected marine areas

All MPA case-studies included

Sensitivity analysis; habitat confounded studies excluded
Log10 (size) (km2) 18 −0.17 [−0.29 → −0.04] QM = 6.78, p = 0.01
Log10(census area) (m2) 15 −0.24 [−0.51 → 0.03] QM = 3.13, p = 0.08
Min. Distance (km) 15 −0.13 [−0.31 → 0.06] QM = 1.82, p = 0.18
  1. Data under sensitivity analysis is given only for the moderator variable which showed considerable different result from when all studies were included.
