The phrase "additional model includes" is correct and usable in written English.
It can be used when specifying that a supplementary model is part of a larger set or collection of items or concepts.
Example: "The additional model includes features that enhance user experience and improve functionality."
Alternatives: "supplementary model comprises" or "extra model contains".
An additional model including income and educational level revealed similar results (data not shown).
As obesity is known to be associated with pre-eclampsia and diabetes, we fitted an additional model including these two variables (prevalence 0.9% and 4.5% respectively).
We also combined glucose and cholesterol together with the other CVD-risk variables in a single model with two strata for sex (Additional file 1: Table A1) and, in an additional model, included the variable "known diabetes".
In an additional model including all possible third and fourth order interactions, the higher order interactions were not statisticially significant and other effects were not changed, and so the model including only second order interactions is shown.
In an additional model including all three exposures among the nonsmokers, the ORs were 3.9 for cutting, cooling, or lubricating oils; 1.9 for antifreeze and coolants; and 2.9 for mineral or white spirits; none was statistically significant (data not shown).
The independent factors for shorter OS (multivariate analysis): male gender, primary tumor ulceration, number of involved nodes ≥4, micrometastases size >1.0 mm, and, in additional model including molecular analysis positive MM-RT-PCR results (hazard ratio [HR] 3.2), micrometastases size >1.0 mm (HR 1.13), and primary tumor ulceration (HR 2.17).
For assessing the relationships between peak Fmed and EAM, an additional model included the mechanical axis angle, a measure of static limb alignment, as a covariate to determine whether the interaction of EAM and mechanical axis angle explained significant variance in the data.
Moreover, we consider two additional models including occasional long-distance trips [8] in models L and M, called L+T and M+T respectively.
The additional models included in the sensitivity analysis are shown in Table 4.
Additional models including interaction terms between migration background and language region or period showed no remarkable differences.
