Paired Wilcoxon signed\u2010rank tests were used to assess differences in exercise and physiological parameters between examinations. Z\u2010tests were used to assess the proportion of changes in\n URT<\/jats:styled-content>\n disorder grade\/appearance between examinations. A McNemar's test was used to compare the proportion of horses with each disorder at each examination. Test\u2013retest reliability across examinations was assessed using Spearman's \u03c1, and ordered logistic regression used to explore temporal effects on repeatability. Lattice plots were constructed to view variability in disorders over time.\n <\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n Seventy\u2010eight horses (median age 2.4 years) with 195 resting endoscopic examinations including 72\/78 horses with 179 pre\u2010exercise and exercising\n OGE<\/jats:styled-content>\n examinations were evaluated. Median time between examinations was 226.5 days with no differences between exercise and physiological parameters. Grades significantly varied between examinations for all disorders, and in particular for palatal instability (\n PI<\/jats:styled-content>\n ) and epiglottic grade at rest. A temporal link between examination interval and disorder grade change was identified for\n PI<\/jats:styled-content>\n and resting arytenoid asymmetry.\n <\/jats:p>\n <\/jats:sec>\n \n Main limitations<\/jats:title>\n \n OGE<\/jats:styled-content>\n re\u2010examinations within a shorter, more consistent time\u2010frame would allow determination of intrahorse variability.
