Predictive value of GCIG CA125 PD/no-PD.

	RECIST PD	No RECIST PD	Total
GCIG CA125 PD	24	19	43	PPV: 56% 95% CI: 40 to 71
No GCIG CA125 PD	18	9	27	NPV: 33% 95% CI: 17 to 54
Total	42	28	70

Positive predictive value (PPV) and negative predictive value (NPV) of GCIG CA125 disease progression (PD) criteria to predict RECIST PD within one cycle of CA125 PD. PPV: probability of patients with CA125 PD also had RECIST PD, NPV: probability that those without CA125 PD also did not have RECIST PD.
