Odds Ratio for Oral Cancer is directly Proportional to the Number of associated Habits

Ordinal regression modelling between proportional odds and non-proportional odds

Which Is the Most Suitable Classification for Colorectal Cancer, Log Odds, the Number or the Ratio of Positive Lymph Nodes?

OBJECTIVE The aim of the current study was to investigate which is the most suitable classification for colorectal cancer, log odds of positive lymph nodes (LODDS) classification or the classifications based on the number of positive lymph nodes (pN) and positive lymph node ratio(LNR) in a Chinese single institutional population. DESIGN Clinicopathologic and prognostic data of 1297 patients w...

177-30: Using SAS® to Estimate Proportional Odds Ratio Model for Meta-Analysis of Diagnostic Tests

This work shows how we can use SAS system to implement the proportional odds ratio (POR) model (Siadaty 2004). POR is used to pool results of several studies together in a meta-analysis of diagnostic tests. It generalizes comparison of competing tests when there are two or more tests available for disease and each test has been studied in one or more papers and each paper might have studied mor...
