Table 4.

Pairwise post hoc comparisons and effect size for individual level response variables in which there was a significant effect of cold storage and/or year of study. “Group 1” and “Group 2” refer to the two groups in the comparison. “CSU” indicates group placed in cold storage unit; “outside” indicates group placed in ambient conditions outside the CSU; “N1” and “N2” columns show sample sizes for Groups 1 and 2, respectively. Effect size (with 95% confidence intervals) were calculated using Hedge’s g: t × ((n1 + n2)/(n1 × n2))^0.5 where t is the t value of the contrast. Contrasts which do not have zero in the effect size s.e. interval are in bold.
