| dc.description.abstract | This check provides an exploratory analysis of patient eligibility criteria for a study. It summarizes each step of attrition criteria in the cohort construction for a given site. |

| local.description.raw | The raw data output of this check produces nine columns of data: <br> |Column |Data Type|Definition | |-------------------|---------|-------------------------------------------------------------------------------------------------------------| |`num_pts` |numeric |the number of patients associated with a given attrition step - provided in the attrition table by the user | |`step_number` |numeric |an integer indicating the step associated with the attrition - provided in the attrition table by the user | |`attrition_step` |character|a string describing the attrition step - provided in the attrition table by the user | |`site` |character|the name of the site being targeted | |`...` | |any additional columns that were included in the user-provided attrition table will also appear in the output| |`prop_retained_prior`|numeric |the proportion of patients retained from the previous attrition step | |`ct_diff_prior` |numeric |the difference in patient count between a given attrition step and the previous step | |`prop_diff_prior` |numeric |the proportion difference between a given attrition step and the previous step | |`prop_retained_start`|numeric |the proportion of patients retained from the user-defined "start" attrition step | {.dqcheck-table} |
| local.description.viz | This check outputs a line graph visualization with a reference table. The user inputs the attrition step at which the visualization should begin and selects a variable to facet by (num_pts, prop_retained_start, prop_retained_prior or prop_diff_prior). Each line represents a site, distinguishable by color. A thick red line represent the 'All Site Median'. Hovering over any point along the graph displays a tooltip with the site name, the description of the attrition step, the patient count and the value of the user-selected variable (ex: prop_retained_start). The accompanying reference table describes all the attrition steps. |
