Inaccurate definition of measurement methods and incorrect units

[hansenp]

In MPD there are many measurements that were not actually measured but calculated from other measurements in the database, such as fold changes or increases in body weight over certain periods of time. For such calculated database entries, the values in the method column were typically retained and, in some cases, the units were not adjusted accordingly.

Example

For the Attie2 project, mice from the fourth week of life were treated with a high-fat, high-sucrose diet and their body weight was measured weekly. If the measurements for the Attie2 Project are filtered to those that have body weight in the Procedure/Protocol column (in the database this column is called method) a total of four categories of measurements remain.

The first category contains the results of the body weight measurements in the different weeks. The second category contains values calculated from these measurements, which represent the increase in body weight compared to the first week of diet, i.e. increase in grams per one week of diet, increase in grams per two weeks of diet, etc. In addition, the increase in body weight in the 17th week of the diet compared to the 10th week of the diet was calculated (category 3). Finally, as part of a glucose tolerance test, an additional measurement of body weight was performed at week 14 of the diet (category 4). A g is given as the unit in all cases, even though the values from categories 2 and 3 refer to specific time periods.

In MPD, there are therefore several measurements for the different weeks of life, which could be interpreted as body weight. For example, for the 21st week of life, three different measurements with the procedure/protocol body weight and unit g are available for each mouse, which only differ in their values, variable names and descriptions. Here are the corresponding distributions of the values of female mice from the project Attie2 for measurements of category 1, 2, and 3:

The values from the different categories are in different ranges. Information from the variable names and descriptions is required for correct interpretation, but these cannot be processed automatically because their formatting does not follow a uniform schema.

To illustrate the problem with the inconsistent formatting, here are all variable names and descriptions of measurement informations that have body weight in the Procedure/Protocol (method) column:
