Table 3 Table shows the estimated contrasts for lumbar flexion between the fat grades with the corresponding standard error (SE), degrees of freedom (df), t-statistic (t), the p-value (p) and the lower and upper bound of the 95% confidence interval (uCL and lCL)

From: Correlation between lumbar dysfunction and fat infiltration in lumbar multifidus muscles in patients with low back pain
