Results quoted from your papers

Are these right?

OpenAgData quotes measured results from papers so that a reader can see what was tested, what was measured and which way it went. These are the 5 results drawn from your paper. You measured them; nobody is better placed to say whether we read them correctly.

Mark a result Right and it is shown as confirmed by its author. Mark it Not right and it comes off the public page until it has been corrected from the paper.

This page was opened without an author's link, so what you mark here goes to a reviewer first and changes nothing on the public page until they have looked.

These are the results the index extracted from each paper's text. Each shows the comparison, what was measured, the direction the paper reports and, where the index holds it, the sentence it was read from. A check is kept with the ORCID iD it was made under and the time it was made.
