| dc.description.abstract | This check provides raw data and visualizations to aid a user in evaluating whether the distribution of quantitative variables aligns with clinical expectations. It can summarize the distribution of a quantitative variable (like lab result values) or patient counts (like number of patients with an outpatient visit). |
| dc.description.abstract | #### How to Access This Check 1. You may access the module's R package in [GitHub](https://github.com/ssdqa/https://github.com/ssdqa/quantvariabledistribution).<br> Or, run in R ```{r} install_github('ssdqa/https://github.com/ssdqa/quantvariabledistribution') ``` 2. Using the provided vignettes on GitHub or help in R, follow parameter input instructions for "Multi Site", "Exploratory", "Longitudinal" requirements. |

| local.description.viz | This check outputs a line graph displaying the user-specified summary statistic of each value type across the time span. Each line represents the distribution of the statistic at each site included in the analysis across the time span. |
