A paper is on the positive side when any of its claims here is positive. 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.
