Table 8 Summary statistics to perform a one-sample t-test based on differences per patient

From: The analysis of continuous data from n-of-1 trials using paired cycles: a simple tutorial

Statistic

Value

Explanation

n

12

Number of patients

Mean

192.74 mL

Mean of the 12 patient means

Variance

9895 mL2

Sample variance of the 12 patient means

SD

99.48 mL

Standard deviation = √variance

SE

28.72 mL

Standard error = SD/√n

DF

11

Degrees of freedom = n-1

t

6.71

t-statistic =192.7 mL/28.72 mL

P-value

< 0.001

Probability under H0 a t-statistic with 32 DF will be ≥ 6.71 or ≤ − 6.71
