I commend Conrad and Becker (2011) for frankly discussing the criteria by which to judge data quality in chemical risk assessment.
A 'star system' was used to judge data quality based on three broad perspectives: selection, comparability and outcome of interest for case-control studies.
Along the same lines, figures that are cropped to a degree that makes it impossible to judge data quality, or that are composed of a dozen down-scaled and now stamp-sized pictures that have lost much of their initial high resolution, are not an uncommon phenomenon these days, even in high impact print journals.
First, SNR should be compared in well-shimmed brain regions (e.g., post PHG) to judge baseline data quality.
By tracking anomalies, detecting inconsistencies, judging plausibility, and gauging data quality, we Question the Frame.
We used the assumption that all of the chromium present in drinking water is in hexavalent form [ 50], and data quality is judged to be moderate based on both the sample sizes ranging from approximately 259 to 329 for the year 2006 in DWSP [ 28], and the comprehensive review of data provided in the guideline document.
Since bowel functions are in focus for residents at these ages in nursing homes and the investigators informed about the study and the necessity of correct data, the data quality has been judged as satisfactory.
Ultimately judging the extent to which our results are impacted by heterogeneous data quality will require comparison with future refinements of the genome sequences and annotations.
Data quality was controlled by comparing data from different sources, with reliability judged by local experts and priority given to official records.
A series of data quality controls were used in the EC_Processor; for example, data quality was judged by atmospheric stability.
