CCF: Cereal-based complementary food. n = number of samples. Mean = arithmetic mean; median = 50th percentile; P90 = 90th percentile; P95 = 95th percentile. MB (LB-UB): middle bound (lower bound-upper bound), LB results below the LOD were replaced with 0; MB: results below the LOD were replaced with LOD/2, UB: results below the LOD were replaced with the value of LOD.
