Introduction:
Inexpensive blood tests have been well established as alternatives to liver biopsies to evaluate liver fibrosis in CHB patients. Here, we aim to compare their diagnostic accuracy in assessing liver fibrosis and necroinflammation.
Patients And Methods:
A retrospective study was performed to evaluate the predictive value of non-invasive models in chronic hepatitis B patients with liver fibrosis by the area under receiver operating characteristic curve (AUROC). The clinical data of 160 patients were collected from medical records.
Results:
Of the 160 consecutive treatment-naïve CHB patients, 29 (16%) had significant fibrosis and 34 (21%) had severe necroinflammation. The AUROC of the gamma-glutamyl transpeptidase to platelet ratio (GPR) (0.761, 95% CI 0.671-0.850) for predicting significant fibrosis was significantly higher than that of the aspartate transaminase-to-platelet ratio index (APRI) (0.680, 95% CI 0.585-0.774, p=0.034), but comparable with the fibrosis index based on four factors (Fib-4) (0.746, 95% CI 0.656-0.836, p=0.703), while for predicting severe necroinflammation, the performance of the GPR (AUROC=0.869, 95% CI 0.800-0.937) was better than the APRI (AUROC=0.816, 95% CI 0.740-0.892, p=0.085) and Fib-4 (0.792, 95% CI 0.711-0.873, p=0.023).
Discussion:
GPR is a satisfactory model to stage liver fibrosis and to grade necroinflammation activity, representing a convenient non-invasive alternative to liver biopsy in China.

Pharmacokinetic Models: Comparison and Selection Criterion
Physiological models take a detailed approach by considering specific molecular processes. They can predict drug distribution, metabolism, and elimination changes, providing a comprehensive understanding of how drugs interact with the body.
Predicting Molecular Geometry
Prediction Intervals
However, the point estimate is most likely not the exact value of the population parameter, but close to it. After calculating point estimates, we construct interval estimates, called confidence intervals or prediction intervals. This prediction interval comprises a range of values unlike the point estimate and is a better predictor of the observed sample value, y.
