Abstract
This check provides raw data and visualizations to aid a user in evaluating whether unmapped values are present in a dataset of interest. It summarizes the proportion of rows & patients with unmapped values, as well as the median number of unmapped rows per patient.
Data Requirements
Probe
Clinical Assessment
Access Package
# install.packages("devtools")
devtools::install_github('ssdqa/https://github.com/ssdqa/unmappedconcepts')Visualization Output
This check outputs a line graph displaying the user-specified numerical statistic of each variable across the time span. Each line represents the distribution at each site included in the analysis across the time span.
Raw Output
This check produces a raw data output containing 15 columns:
| Column | Data Type | Definition |
|---|---|---|
site |
character | the name of the site being targeted |
time_start |
date | the start of the time period being examined |
time_increment |
character | the length of each time period |
variable |
character | the name of the variable being investigated for unmapped values |
total_rows |
numeric | the total number of rows associated with the variable |
total_pt |
numeric | the total number of patients associated with the variable |
unmapped_rows |
numeric | the number of unmapped rows associated with the variable |
unmapped_pt |
numeric | the number of patients with at least one unmapped row associated with the variable |
unmapped_row_prop |
numeric | the proportion of unmapped rows |
unmapped_pt_prop |
numeric | the proportion of patients with at least one unmapped row |
median_all_with0s |
numeric | the median number of unmapped rows per patient, for all patients, across all sites |
median_all_without0s |
numeric | the median number of unmapped rows per patient, for only patients with evidence of the variable, across all sites |
median_site_with0s |
numeric | the median number of unmapped rows per patient, for all patients, across a specific site |
median_site_without0s |
numeric | the median number of unmapped rows per patient, for only patients with evidence of the variable, for a specific site |
output_function |
character | a string indicating the type of visualization that should be generated by uc_output |
