Incidence of hepatitis B virus infection among human immunodeficiency virus-infected treatment naïve adults in Botswana.
Article in Medicine, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 papers.
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
Hepatitis B virus (HBV) and human immunodeficiency virus (HIV) coinfection is highest in sub-Saharan Africa and results in accelerated clinical outcomes compared with HBV or HIV mono-infection. HBV clearance rates are higher in healthy adults; however, in sub-Saharan Africa, there are limited data on clearance of incident HBV in HIV-infected adults. Therefore, we sought to estimate HBV incidence and HBV surface antigen (HBsAg) clearance in HIV-infected adults in Botswana.This was a retrospective longitudinal study of 442 HIV-1C infected treatment naïve patients enrolled in a previous Botswana Harvard AIDS Institute Partnership study. Archived plasma samples from 435 HIV-infected treatment naïve participants were screened for HBsAg and HBV core antibody (anti-HBc). HBsAg was evaluated annually over a 4-year period, and HBV deoxyribonucleic acid (DNA) levels of HBsAg-positive chronic and incident patients were quantified.Baseline median CD4+ T-cell count was 458 cells/μL [Q1, Q3: 373, 593], and median HIV viral load was 4.15 copies/mL [Q1, Q3: 3.46, 4.64]. Twenty two HBV incident cases occurred, representing an incidence of 3.6/100 person-years [95% CI: 2.2-5.6]. All incident HBV cases with a follow-up sample available for screening (13/22) cleared HBsAg. Detectable HBV viral loads among chronic and incident cases ranged between 5.15 × 10 to 1.4 × 10 IU/L and 1.80 × 10 to 1.7 × 10 IU/mL, respectively.We report high HBV incidence associated with elevated HBV DNA levels despite high CD4+ T-cell counts in HIV-infected patients in Botswana. These incidence cases represent a potential source of HBV transmission in the population. Scaling-up of HIV treatment strategies utilizing antiretroviral therapy regimens with anti-HBV activity coupled with screening for HBV infections in households of the HBsAg-positive cases is recommended.
