Figure 4. Model-based Prediction of the Simple Reaction Time Test Illustrating the Interaction of Highest Grade Achieved with H. pylori and CagA.

Data are model-based predictions of the interaction of education with H. pylori and CagA on the Simple Reaction Time Test (SRT) controlling for latent toxoplasmosis, age, gender, race-ethnicity, PIR, health, and hemoglobin. Higher SRT values indicate poorer cognitive function.
