Note: The 368 dogs diagnosed with AKI for which complete vaccination information was available were stratified based on their L4‐vaccination status. P refers to the statistical significance of the Kruskal‐Wallis one‐way ANOVA (continuous variable: age) or of the chi‐square test (categorical variables: sex, neuter status, breed group).
Abbreviations: L0, not vaccinated with L4; L4−, partially vaccinated with L4; L4+, correctly vaccinated with L4; IQR, interquartile range.
