The Sig. (2-tailed) column displays the probability of obtaining a t- statistic whose absolute value is equal to or greater than the obtained t-statistic.Since the significance value for change in weight is less than 0.05, you can conclude that the average loss of 8.06 pounds per patient is not due to chance variation, and can be attributed to the diet. However, the significance value greater than 0.10 for change in triglyceride level shows the diet did not significantly reduce their triglyceride levels. The paired-samples t-test is appropriate whenever two related sample means are to be compared.
