From: Breast cancer risk in papilloma patients: Osteopontin splice variants indicate prognosis
Osteopontin splice variants are indicators for prognosis. The bar graph shows mean ± standard error of the pathology scores (staining intensity, percent positivity, additive score) for OPN-c (antibody F2), OPN-exon-4 (antibody MAB193P), evaluation of both combined together. The additive scores were obtained by adding their component scores (intensity plus percent positivity). ca = cancer developed, none = no progression, cl = later diagnosis of cancer in the contralateral breast. The bottom panel shows the p-values for two-tailed and one-tailed t tests (assuming elevation in the progressors) for comparisons among the patient groups. Values below 0.05 are displayed in italics
