In studies with paired samples of continuous data the mean difference is usually compared to zero. Instead of a paired t-test also a Bayesian analysis on the mean difference is possible. A traditional paired t-test of two treatment modalities on hours of sleep provided a significant difference with t = 3.184, p-value = 0.011.

A paired-samples t-test compares the mean of two matched groups of people or cases, or compares the mean of a single group, examined at two different points in time. If the same group is tested again, on the same measure, the t-test is called a repeated measures t-test.

Comparison of 2 means for matched observations (paired t test) and t test assumptions
American Journal of Orthodontics and Dentofacial Orthopedics, 2015Variable n Mean (mm) SD (mm) Resorption 74 2.10 0.95 When we are making measurements before and after an intervention or at the same time on different sites (split-mouth design) in the same patient, we use a paired t test. The results before and after the intervention or in a split-mouth trial do not comprise 2 independent samples because both samples ...

A Generalization of the Paired t-Test
Applied Statistics, 1982The analysis of paired data with a variable number of readings per pairing is discussed. The standard t‐test based on paired means is not valid if there is within‐pairing variability. A generalized paired t‐test is developed and a numerical example is given.

Paired Continuous Data (Paired T-Test, Wilcoxon Signed Rank Test)
2016Studies where two outcomes in one patient are compared with one another, are often called crossover studies, and the observations are called paired observations. As paired observations are usually more similar than unpaired observations, special tests are required in order to adjust for a positive correlation between the paired observations.

How Do We Perform a Paired t-Test When We Don’t Know How to Pair?
American Statistician, 2022We address the question of how to perform a paired t-test in situations where we do not know how to pair the data. Specifically, we discuss approaches for bounding the test statistic of the paired t-test in a way that allows us to recover the results of ...
