Notes: Data expressed as mean ± standard deviation in%. Fair Grey tone background (whatever contiguous cell) means significant differences compare to all other age clusters, within a same ethnic group. Same grey tone (only for medium and dark) for contiguous cells illustrates non-significantly different values through age clusters, within same ethnic group. A group of contiguous cells with same grey tones (medium and dark) are significantly different compare to all other age clusters, within same ethnic group.
