One entity, such as intervention rapamycin or disease sarcopenia, with the papers that involve it, newest first, and the role it plays in each. For an intervention, a gene or a process, evidence gives its evidence as structure, never as a grade: the species its findings reach and whether independent labs found the same there, the labs and countries behind them, the findings against, its trials and those with no results posted, its funders and its company ties. A synonym or an old key answers with the entity it now names.
