A commentary by researchers from the Johns Hopkins Bloomberg School of Public Health suggests that analytic research data should be made available so that reproducibility of epidemiologic studies can be the new minimum standard for which investigators strive.

Q&A: Researchers from the Johns Hopkins Bloomberg School of Public Health today published a study in the Journal of the American Medical Association relating hospital admissions with fine particulate matter levels. In a study of 204 U.S. urban counties, for every 10 µg/m3 increase in particulate matter, the researchers calculated 11,000 additional cardiovascular and respiratory disease hospitalizations among the Medicare participants who participated in the study.

Short-term exposure to fine particulate matter—the microscopic particles that pollute the air—increased hospital admissions for cardiovascular and respiratory disease among Medicare participants.
