1 · What the graph read from it

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.

2 · The registry

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

objectiveChina's national hepatitis burden is high. This study aims to provide a detailed national-level description of the reported incidence of viral hepatitis in China during 2004-2016.

designObservational study.

settingData were obtained from China's National Notifiable Disease Reporting System, and changing trends were estimated by joinpoint regression analysis.

participantsIn this system, 16 927 233 reported viral hepatitis cases occurring during 2004-2016 were identified. PRIMARY OUTCOME MEASURE: Incidence rates per 100 000 person-years and changing trends were calculated.

resultsThere were 16 927 233 new cases of viral hepatitis reported in China from 2004 to 2016. Hepatitis B (HBV) (n=13 543 137, 80.00%) and hepatitis C (HCV) (n=1 844 882, 10.90%) accounted for >90% of the cases. The overall annual percent change (APC) in reported cases of viral hepatitis and HBV were 0.3%(95% CI -2.0 to 0.8, p=0.6) and -0.2% (95% CI -1.6 to 1.2, p=0.8), respectively, showing a stable trend. HBV rates were highest in the 20-29 year old age group and lowest in younger individuals, likely resulting from the universal HBV vaccination. The reported incidence of HCV and hepatitis E (HEV) showed increasing trends; the APCs were 14.5% (95% CI 13.1 to 15.9, p<0.05) and 4.7% (95% CI 2.8 to 6.7, p<0.05), respectively. The hepatitis A (HAV) reporting incidence decreased, and the APC was -13.1% (95% CI -15.1 to -11.0, p<0.05). There were marked differences in the reporting of hepatitis among provinces.

conclusionsHBV continues to constitute the majority of viral hepatitis cases in China. Over the entire study period, the HBV reporting incidence was stable, the HCV and HEV incidence increased and the HAV incidence decreased. There were significant interprovincial disparities in the burden of viral hepatitis, with higher rates in economically less-developed areas. Vaccination is important for viral hepatitis prevention and control.
