Median, standard deviation (SD), 95% credible intervals (CI) of contrasts between posterior estimates, Posterior probability (PP), evidence ratio (ER), ER01 in favour of the directional hypothesis (PP> 0) and ER10 in favour of the altenrative hypothesis (PP < 0), bold = posteior probability exceeds 85%; star = posterior probability exceeds 95%.
