Table 2 Summary of the weighted simple random-effects regression models for each of the four moderator variables on fish assemblage density effect size

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

All MPA case-studies included
Moderator variable N oMPAs Slope [95% CI] Q M, p-val
MPA age (year) 21 −0.001 [−0.03 → 0.03] QM = 0.007, p = 0.94
Log10 (size) (km2) 21 −0.002 [−0.24 → 0.23] QM = 0.0004, p = 0.98
Log10(census area) (m2) 19 −0.005 [−0.31 → 0.30] QM = 0.001, p = 0.97
Min. Distance (km) 19 0.28 [0.18 → 0.37] QM = 31.59, p < 0.0001
Sensitivity analysis; habitat confounded studies excluded
Min. Distance (km) 15 −0.23 [−0.65 → 0.19] QM = 1.17, p = 0.28
  1. Data under sensitivity analysis is given only for the moderator variable which showed a considerably different result from when all studies were included.
