Seven PNC subgroups: PNC(E) – The exclusive PNC provider for one pregnancy. PNC(M) – this provider served more than half of all visits for one pregnancy. PNC(U) – the uniquely most frequently visited provider, who is the only one who served the most visits for a patient. PNC(MFVI) - most frequently visited provider, who served the most visits and the first visit for a patient. PNC(MFVF) - most frequently visited provider, who served the most visits and the last visit for a patient. PNC(MFVIF) - most frequently visited provider, who served the most visits, first and the last visits for a patient. Dispersal PNC: the number of total PNC visits equals the number of total providers
