  • a Staining results were grouped in the indicated ranges of percentage of tumor cell staining for each antibody for purposes of data presentation.

  • b Numbers represent total number of tumors for each percentage of tumor cell staining for each antibody. Because the total number of specimens was 101, no percentages are given.
