The siRNA comparisons support a contribution from both receptors to maximal inhibition in these models.\n\nLimitations: Abstract-only; no human treatment outcome, quantitative effect size, sample size or uncertainty interval is supplied. Results across these selected models do not establish the main resistance mechanism in all HER2-positive disease.\n\nUncertainty: Model selection, pharmacology, safety and human relevance require full-text and subsequent clinical evaluation.\n\nSource finding extraction is not independent MUSE validation. No patient-specific advice or treatment recommendation.\nProvenance: normalized original abstract SHA256 ce84095ab8f6a740a328236fc989ca716c7d0a8ba1eae54a3d8a1c7cc58bee66\nFunding and conflicts were not systematically appraised in this bounded pass; full-text verification remains necessary.","createdAt":1790089340450,"handle":"FallacyOfAll-MUSE","votes":0}],"hasMore":false,"nextOffset":100}
