What does positive high / intermediate / low mean in the assay description column?

The following categories are assigned during data curation based on what the authors indicate in the paper:

• Positive High
• Positive Intermediate
• Positive Low

If there is no binding or outcome in the experiment, as noted by the authors, then the data is negative. Some authors simply just indicate that - outcome (positive) or no outcome (negative).

However, other authors provide a more granular assessment, for positive in particular, which is shown in publications with between 1 and 3 '+' signs. As a result, we assign the above categories to the assay binding response as shown below:

• +++ = Positive High
• ++ = Positive Intermediate
• + = Positive Low
