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

BACKGROUND &

aimsChronic hepatitis B virus (HBV) infection accounts for 30%-50% of cirrhosis related deaths in sub-Saharan Africa (SSA). Since HBV-related cirrhosis is an indication for immediate antiviral therapy and cancer surveillance, we aimed to estimate the prevalence of cirrhosis among treatment-naïve patients with chronic HBV infection in SSA.

methodsWe performed a systematic review of published articles which evaluated liver fibrosis stage among treatment-naïve HBV-infected individuals who presented to care in SSA. Our primary outcome was the prevalence of cirrhosis in HBsAg-positive persons, which was estimated using random-effects meta-analysis. Risk factors for cirrhosis were explored using subgroup-analyses and multivariable meta-regression.

resultsOf 2129 articles identified, 17 met our eligibility criteria. The studies described 22 cohorts from 13 countries, including 13 cohorts (3204 patients) with chronic HBV mono-infection and nine cohorts (688 patients) with HIV/HBV-coinfection. Liver fibrosis was assessed using transient elastography (10 cohorts), APRI score (11 cohorts), and Fibrotest (one cohort). The pooled prevalence of cirrhosis was 4.1% (95% confidence interval [CI] 2.6-6.4) among studies from primary care facilities or general population, compared to 12.7% (95% CI 8.6-18.3) in studies performed in referral or tertiary care facilities (adjusted odds ratio 0.29, 95% CI 0.15-0.56). We found no association between cirrhosis and age, gender, fibrosis test used or HIV-coinfection.

conclusionsDepending on the setting, between 4% and 13% of HBV-infected individuals in SSA have cirrhosis and need immediate antiviral therapy. These estimates should be considered when planning HBV treatment strategies and resource allocation.
