Yes this it is! The research was not intended for the public benefits instead it was to fulfill my own needs. No publication was made to inform the public about its findings, it remained to be my secret with those who informed me about linea nigra and its applicability to women. Trust me please linea nigra is faint in young ladies and sometimes it is not visible at all. In adult women who have already given an infant, the line is well marked and visible. The number of sample for myself is small but if combined with those of the 'washkaji' who conviced me to excute the research, it bring us into conclusion!
