In this short overview the principles of evidence-based medicine are introduced and their relevance for small animal practice is discussed. The hierarchic order of evidence is presented, with meta-analyses of many studies or systematic reviews being the most reliable evidence possible, followed by randomized controlled trials, case series, case reports and published expert committee opinions and lastly personal experiences. Evidence of higher quality should overrule contradictory evidence of lower quality, always considering the individual circumstances of the patients and the owner's wishes.
在本简短综述中，介绍了循证医学的原则，并讨论了其在小动物临床实践中的相关性。文中呈现了证据的等级顺序，多项研究的荟萃分析或系统评价是最可靠的证据，其次是随机对照试验、病例系列、病例报告以及已发表的专家委员会意见，最后是个人经验。高质量的证据应推翻低质量的矛盾证据，同时始终要考虑患者的个体情况和主人的意愿。
