+  "reasoning": "The original claim was a semantic duplicate of two existing claims already in the KB, attempting to merge their content without retiring the originals. The new claim restated essentially the same evidence (deficiency rates, iron/calcium/protein intake figures, 92% no dietitian support, dual mechanism, food insecurity compounding). The reviewer feedback consistently highlighted this as a critical issue, recommending enrichment of existing claims rather than creation of a new, overlapping one. The third candidate is related as it discusses the sarcopenic malnutrition risk, which is a direct consequence of the nutritional deficiencies discussed."
