Table 1.
Comparison of two linear models of response (mean foci per cell count) and statistical significance of response predictors.
| Variables (Levels) | Model 0 | Model 1 |
|---|---|---|
| Beam (BB/MRT) | ***/*** | ***/*** |
| Well (Well 2) | *** | *** |
| Distance (D2) | *** | *** |
| p53 status (null) | ns | ns |
| Time (4 h/24 h) | ***/*** | ns/*** |
| Well (Well 2)/Time (4 h/24 h) | na | **/*** |
| p53 status (null)/Time (4 h/24 h) | na | ns/** |
| Beam (BB)/Well (Well 2) | na | * |
| AIC – Akaike’s Information Criterion | 1993.7 | 1941.0 |
| χ2 – chi squared statistics/difference in degrees of freedom for Likelihood Ratio Test (LRT) | 62.7/5 | |
| p – value (LRT) | <0.001 |
In parenthesis, levels of variables are indicated for which statistical significance of effect was calculated relative to the baseline, as defined in the text. Statistical significance codes: ***p < 0.001, **p < 0.01, *p < 0.05, ns - p > 0.05, na – not applicable.
