From the article: As far as I can tell, the justification for the quote is probably in Table 1, col. 1. Baseline mortality rate (white newborn + white dr) is 290 (per 100k). Black newborn is +604 above that giving 894/100k. Then -494 from that when it is black newborn + black dr giving 400/100k. So the black newborn mortality rate is more than cut in half when the doctor is also black. Black newborn survival rate 894/100k. Survival odds = (100k-894)/894, or about 111-to-1. Black newborn + black dr survival rate 400/100k. Survival odds (100k-400)/400, or about 249-to-1.
