The records of 200 colic episodes, collected prospectively, over a two year period, from first opinion cases, were analysed and compared with a control sample selected at random from the same population. Analysis by colic type revealed 72% spasmodic/undiagnosed; 7% surgical; 5.5% flatulent; 5% pelvic flexure impactions; 9.5% other implications and 1% colitis. A possible predisposing cause was identified in 43% of the spasmodic/undiagnosed cases. The total incidence of colic in each age group showed no statistically significant differences from the control population. Stallions were significantly under represented in the colic population. When compared with the control sample the number of spasmodic/undiagnosed colic cases in the 5-10-year-old group and the number of surgical colics in the over 15-year-old group were significantly greater than expected. No statistically significant correlation was found when the seasonal incidence of colic was compared with monthly temperature, change in monthly temperature, monthly rainfall, and rainfall weighted for temperature.
前瞻性收集了两年内来自初诊病例的200起绞痛发作记录，并与从同一人群中随机选取的对照样本进行分析和比较。按绞痛类型分析显示，痉挛性/未确诊的占72%；外科性的占7%；气胀性的占5.5%；骨盆曲部阻塞性的占5%；其他情况的占9.5%；结肠炎的占1%。在43%的痉挛性/未确诊病例中确定了可能的诱发原因。各年龄组绞痛的总发病率与对照人群相比无统计学显著差异。种马在绞痛病例中所占比例明显过低。与对照样本相比，5至10岁组的痉挛性/未确诊绞痛病例数以及15岁以上组的外科性绞痛病例数显著高于预期。将绞痛的季节性发病率与月气温、月气温变化、月降雨量以及根据气温加权的降雨量进行比较时，未发现统计学显著相关性。
