Awarded prices from public tenders (source II of IN SEGES/ME 65/2021). We compare the items the search found by text, in the same unit. Prices below 50% or above 150% of the group median, taken before this cut, are left out. The list shows up to 50 prices, each with its reference. Besides PNCP, we use TCE-CE and Compras.gov.br. When a purchase reaches PNCP, its price moves there and is not counted twice.
