Significance
Significance (Medicine)
Significance (pronounced sig-nif-i-kans) is a term used in the field of medicine to denote the importance or relevance of a particular finding, symptom, or medical condition. It is derived from the Latin word 'significans', which means 'indicating'.
Medical Significance
In the context of medicine, significance can refer to the importance of a symptom, test result, or medical condition in diagnosing, treating, or understanding a patient's health. For example, the significance of a high blood pressure reading may indicate a risk for cardiovascular disease.
Statistical Significance
In medical research, statistical significance refers to the likelihood that a result or relationship is caused by something other than mere random chance. Statistical significance is usually expressed as a p-value, with a p-value of less than 0.05 often being considered statistically significant.
Clinical Significance
Clinical significance, on the other hand, refers to whether a treatment's effect is large enough to be meaningful in real-world practice. This is different from statistical significance, as a treatment can have a statistically significant effect but not a clinically significant one.
