2016 ACVIM Forum Research Abstract Program

Analysis for PPID+/HI+ and PPID-/HI+ horses was evaluated. Based on the data for clinical signs only in the PPID-/HI+ horses, HI was significantly (P < 0.000) greater among horses with cresty neck and laminitis present. Although not statistically significant (P > 0.025), HI was greater in horses with 2 other clinical signs; abnormal sweating and pot belly/weight gain. Based on clinical signs data, the odds of HI in horses with cresty neck was more than twice (2.3X) that for horses without this clinical sign. Similarly for horses with laminitis, the odds ratio of HI was more than twice (2.2X) that for horses without this clinical sign.
