Note: The 368 dogs diagnosed with AKI for which complete vaccination information was available were stratified based on their diagnosis. P refers to the statistical significance of a Kruskal‐Wallis one‐way ANOVA (continuous variable: age) or of the chi‐square test (categorical variables: sex, neuter status, breed group).
Abbreviations: AKI‐L, acute kidney injury due to leptospirosis; AKI‐nL, acute kidney injury from other causes than leptospirosis; IQR, interquartile range.
