The rheumatoid arthritis data
Description
Data obtained from a meta-analysis that aimed to determine whether anti-cyclic citrullinated peptide (anti-CCP) antibody identifies more accurately patients with rheumatoid arthritis than rheumatoid factor (RF) does. We include N=22 studies that assessed both RF and anti-CCP2 antibody for diagnosing rheumatoid arthritis.
Format
A data frame with 22 observations on the following 8 variables.
- TP1
the number of true positives for RF
- FN1
the number of false negatives for RF
- FP1
the number of false positives for RF
- TN1
the number of true negatives for RF
- TP2
the number of true positives for anti-CCP2
- FN2
the number of false negatives for anti-CCP2
- FP2
the number of false positives for anti-CCP2
- TN2
the number of true negatives for anti-CCP2
