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

Chronic hepatitis B virus (HBV) infection is a major risk factor for hepatocellular carcinoma (HCC), and surveillance is recommended for patients without cirrhosis when risk exceeds an incidence rate (IR) of 0.2%. Populations in Asia and sub-Saharan Africa have been associated with HCC at younger ages, but the risk after immigration to Western countries should be investigated. The aim of this study was to study HCC by age and country of origin in people with chronic HBV infection in Sweden. Through national registers, residents with chronic HBV diagnosis (1990-2015) were identified with information on country of origin, immigration/emigration, death, coinfections, antiviral therapy, and HCC. Observation time started at HBV diagnosis, and IR and hazard ratios for HCC were calculated by sex, age, and region of origin. Among 16,410 individuals (47% women), the origin and observation time (person years) were as follows: Western Europe, 2316 (25,415); Eastern Europe, 2349 (26,237); Middle East/North Africa, 4402 (47,320); sub-Saharan Africa, 3677 (30,565); Asia, 3537 (35,358); and other, 129 (1277). There were 232 individuals with HCC (82% in men). The IR increased with age and exceeded 0.2% for Asian men from age group 40-49 years (IR, 0.63; 95% confidence interval, 0.39-1.00), for men of other origins from age group 50-59 years, and for women aged ≥60 years originating from Eastern Europe, Asia, and Middle East/North Africa. After exclusion of patients with cirrhosis or HBV treatment, the IR still exceeded 0.2% in Asian men aged 40-49 years. This study demonstrates that HBV-infected men of Asian origin should be recommended HCC surveillance at younger ages, but there is a need for further studies of HCC incidence in African-born men without cirrhosis living in the Western world.
