COX-1 and COX-2 protein expression in ovarian cancer. The percentage of tumor cells positive for COX-1 and COX-2 was determined by automated image analysis and then scaled by intensity for H-scores, ranging from 0 to 300. a Pearson correlation between expression levels of COX-1 and COX-2. H-scores for COX-1 and COX-2 expression in (b) serous, endometrioid, mucinous and clear cell tumors, and in (c) serous tumors versus all other epithelial tumors and type II tumors (high grade serous and high grade endometrioid) versus type I tumors (all other types). P-values from Student’s t-tests
