Figure.

The figure is a pictorial representation of the breakdown of cancer cases found by the clinics. The figure consists of 12 interconnected boxes. The boxes illustrate the process by which the 40 new or reclassified American Indian cases were found. The first box at the top represents the full 266 case sample. This sample is then split into reportable (n = 254) and nonreportable (n = 12) cases. The reportable cases are further split between those that could be linked to the registry (n = 226) and those that could not (n = 28). Of the 226 cases that could be linked to the registry, 181 were classified as AI/AN, 22 were classified as non-AI/AN, and 23 did not match on AI/AN classification. Of the 23 cases that did not match on AI/AN classification, 16 were American Indian in clinic but not registry data, and 7 were American Indian in registry but not clinic data. Of the 28 clinic cases that could not be linked to a state registry, 4 were not American Indian, and 24 were. The final 2 shaded boxes total the 40 cases that were not in the registry or were reclassified as American Indian.
