- CI confidence interval, df degrees of freedom, k effect sizes, LB lower bound, n datasets, PI prediction interval, SMCR Standardized mean change,
SEÂ standard error, UBÂ upper bound. In the orchard plots the estimate (open circle), the confidence interval (horizontal thick black line), and the prediction interval (horizontal thin line) can be distinguished. Furthermore, the size of the color filled circles corresponds with the precision of the effect size
