Yearling laryngeal function in Thoroughbreds that underwent a laryngoplasty differs from controls

Abstract

Background: Yearling laryngeal function (YLF) is frequently assessed at the time of sale and the outcomes of these assessments can have significant economic implications. The YLF of horses that subsequently underwent a prosthetic laryngoplasty (PL) is unknown. Objectives: We hypothesised horses with YLF ≥grade II.2 would be at increased risk of requiring PL, compared with YLF < 0.001), grade III.1: 13.8 (6.0, 31.6, p < 0.001), grade III.2: 55.5 (10.3, 299.2, p < 0.001), grade III.3: 2930,000 (398173.7, 21 600,000, p < 0.001), grade IV: 26300,000 (3 420 000, 202 000 000, p < 0.001). Yearling LF ≥grade II.2 had an OR of 4.61 (3.0, 7.1, p < 0.001) compared with < 0.001) compared with
