Table 5 Decomposition of effects from mediation analysis for the effects of T on NliceM_std that are direct or mediated through IP

From: Parasitic sea louse infestations on wild sea trout: separating the roles of fish farms and temperature

Effect Estimate SE Interpretation
Natural direct effect -0.43 0.054*** The increase in log(NliceM) brought about by a 1 SD increase in T with IP held constant at an average T
Natural indirect effect 0.34 0.038*** The increase in log(NliceM) brought about by increasing IP by the amount that would result from a 1 SD increase in T while holding T constant at an average T
Total effect -0.1 0.046* The increase in log(NliceM) brought about by increasing T by 1 SD
