showed a trendP =0.12
The inclusion of center-based cluster effects showed a trend towards ( P =0.12) improved model fit compared with fitting the same model using ordinary logistic regression with no clustering.
The inclusion of center-based cluster effects showed a trend towards ( P =0.12) improved model fit compared with fitting the same model using ordinary logistic regression with no clustering.
Similarly, the inclusion of cluster effects resulted in a strong trend towards improved model fit (χ 2 =3.27, P LRT =0.071) compared with the base model without the random term for participating centers.
The model revealed highly significant negative associations between older age and higher baseline NIHSS score and mRS90 ≤2.
