Data Quality in Epidemiological Research
Overview
Data quality assessments guided by a 'data quality framework introduced by Schmidt and colleagues, 2021' doi:10.1186/s12874-021-01252-7 target the data quality dimensions integrity, completeness, consistency, and accuracy. The scope of applicable functions rests on the availability of extensive metadata which can be provided in spreadsheet tables. Either standardized (e.g. as 'html5' reports) or individually tailored reports can be generated. For an introduction into the specification of corresponding metadata, please refer to the 'package website' https://dataquality.qihs.uni-greifswald.de/VIN_Annotation_of_Metadata.html.
- HTML report tables now keep numeric descriptive statistics aligned with their variables when some results are empty.
- Summary pie charts now display percentages consistently with one decimal place in both ggplot2 and Plotly output.
- HTML report tables now keep their column headers visible while scrolling and recalculate column widths after responsive resizing with both the DT and DT2 backends. Metadata tables again reveal and hide automatically generated variables even when the displayed label differs from the variable name.
- Fixed automatic study-data discovery in
dq_report_by()so dataframe-level metadata remain separate from study records. This restores dataframe-level integrity results and prevents study records from appearing on metadata report pages. Overview calls no longer claim thatstudy_datawas supplied when it was discovered from dataframe-level metadata, preserve the distinction between omitted and explicitly empty response-variable selections, and correctly filter item-computation metadata for selected response variables.
