dc.description- Systolic and diastolic blood pressure display very uniform behavior amongst the sites and do not seem to have any notable outliers. The mean and median are also relatively similar. - Nationwide is a major outlier for eGFR values, which will require further investigation. Most other sites behave relatively consistently. - Urine protein has a wide array of site distributions which all seem to be quite skewed given the differences between the mean and median. This could be due to unit reporting inconsistencies in this lab type amongst the various institutions. Futher investigation is needed to determine if conversion is required.
dc.description.abstractThe results of a Quantitative Variable Distribution check using the Multi-Site, Exploratory, Cross-Sectional parameters. This check evaluates blood pressure, eGFR, and urine protein distributions at each institution.

dc.provenanceThis data quality check was run on a database extracted from the The Preserving Kidney Function in Children With CKD (PRESERVE) Study. These results were not used for the study, but rather run on the study data after analysis was conducted as part of an SSQDA demonstration project.
