VALIDATION OF THE PAGE-B SCORE AS A PROGNOSIS OF DEVELOPMENT TO HEPATOCELLULAR CARCINOMA (HCC) IN CHRONIC HEPATITIS B, IN THE BRAZILIAN POPULATION.
Observational study in Arquivos de gastroenterologia, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
contextDue to the potential risk for chronic and severe progression, hepatitis B virus (HBV) infection requires antiviral medications, such as Tenofovir (TDF) and Entecavir (ETV), to reduce the HBV viral load and prevent the risk of liver cirrhosis and hepatocellular carcinoma (HCC). The PAGE-B score is a simple and reliable tool for assessing the risk of developing HCC, although it has not yet been validated in Brazil.
objectiveTo validate the PAGE-B risk score for predicting HCC development in HBV carriers in Brazil. To analyze the association between the PAGE-B score and demographic, laboratory, and HBV treatment variables.
methodsAn observational cohort. retrospective study. Study sample - 659 individuals with chronic HBV mono-infection treated with antivirals for at least 3 years at two reference centers in Brazil's Northeast and Amazon regions. The PAGE-B score was used to analyze its association with sex, age, and platelet count, classifying each patient's HCC risk as low, moderate, or high.
resultsThe mean PAGE-B score was 12.77±5.63. PAGE-B scores were classified as low, moderate, and high in 206 (31.2%), 287 (43.5%), and 166 (25.3%) individuals, respectively. Among the 659 patients, 31 (4.7%) developed HCC, a higher frequency than reported in PAGE-B score validation studies from other countries. Of these patients, 29 were male, with a mean age of 57.4±12.6 years and lower platelet levels (<200,000 10³/mL). Patients who developed HCC had fibrosis stages: F0-F1:6 (19.3%); F2:2 (6.4%); F3:2 (6.4%); and F4:21 (67.7%). High-risk patients were treated with ETV (n=129, 32%) versus TDF (n=37, 14,4%), P<0.00.
conclusionThe PAGE-B score demonstrated, in the Brazilian population, a performance similar to that observed in studies with European and Asian populations in terms of sensitivity, specificity, and predictive values for HCC prediction. Based on these results, the PAGE-B score can be used in the Brazilian population to predict the risk of HCC.
