Abbreviations: PA, percentage of agreement, RP, relative position; RC, relative concentration; CI, confidence interval.
Absolute values of RP/RC ≤ 0.01 are assigned value 0.
a
Statistically significant disagreement (absolute value of RP/RC ≥ 0.1 and 95%CI does not include 0, marked in bold).
b
Tendency towards a non-negligible disagreement (absolute value of RP/RC ≥ 0.1 and asymmetric 95%CI around 0).
