Evaluating bias in electronic health record data: using agent-based models to examine whether geographic disparities in community-acquired methicillin-resistant Staphylococcus aureus are due to differential health care-seeking behaviors.
Article in American journal of epidemiology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Electronic health records (EHRs) are increasingly used in public health research. However, biases may exist when using EHRs due to whether someone is captured in the data. Assessing the impact of bias in generating disparities identified with EHR data is difficult because information about health care-seeking behaviors is not included in the record. We developed an agent-based model (ABM) to simulate the health care-seeking behavior for community-acquired methicillin-resistant Staphylococcus aureus infection in a subregion of California. The ABM assumed no difference in prevalence across the study area. We modeled the health care-seeking process to see if geographic differences in prevalence would emerge from the ABM when only looking at those who sought treatment, matching empirical data. The ABM reproduced prevalence in observed data for 9 of the 21 geographies. Simulated differences in prevalence across geographies did not reach the magnitude in observed data, and spatial patterns had low to moderate agreement. Our results suggest that geographic disparities in the methicillin-resistant Staphylococcus aureus prevalence previously identified in California EHR data may be due to determinants beyond bias and health care-seeking behaviors. Future studies could adapt this model for other health outcomes by adjusting the health care-seeking behavior parameters and modifying the disease progression process.
