Questions

126,874 questions on 3,575 organisms, each asked by at least two papers: an organism, a treatment and what it was tested against. In 3,906 of them, a pair of papers with results that differ was accepted in a claim-by-claim check; 48,204 more have positive and negative results with no pair accepted.

Claims are grouped by organism, treatment and what was measured or targeted. Claims that compare genotypes are left out; a claim about lacking a nutrient counts the other way round in that nutrient’s question. “Results differ” marks a question where two model reviewers, reading both claims, accepted at least one pair of papers whose results differ.
