TABLE 6.
Multilevel mixed effects linear regression: association between wall shear stress (WSSTmean Max) and smooth muscle cell (SMC) count. The fixed effects part of the model tests the effect of WSSTmean Max on SMC count. Random effects part of the model tests the effect of the data being nested with the patient domain.
| Coef | Standard error | 95% CI | p Value | |
|---|---|---|---|---|
| WSSTmean Max | −4.87 | 2.240 | −9.26–0.48 | 0.030 |
| Patient | 62.94 | 84.2 | 4.58–865.54 | — |
| Var (estimate SMC count) | 504.31 | 116.15 | 321.11–792.05 | — |
| Likelihood ratio test vs linear model | — | — | — | 0.167 |
