Hepatitis B Surface Antibody Clearance After Vaccination in People With HIV.
Article in Open forum infectious diseases, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Background: People with HIV (PWH) are at higher risk of developing chronic hepatitis B, and therefore vaccination against HBV is highly recommended. Clearance of hepatitis B surface antibody (anti-HBs) over time is poorly described in PWH. Methods: We retrospectively included vaccinated PWH with anti-HBs ≥10 IU/L from the French Dat'AIDS database. Those with a cured hepatitis B were excluded. For each participant, all anti-HBs levels were collected until March 2024. Anti-HBs peak was defined as the highest anti-HBs value and corresponded to entry into the analysis. Factors associated with anti-HBs clearance below 10 IU/L were identified using a multivariable Cox model. Results: 11 082 PWH were included, 4480 had peak anti-HBs levels between 10 and 99 IU/L, 3268 between 100 and 499 IU/L, 1205 between 500 and 999 IU/L, and 2129 ≥ 1000 IU/L. Median follow-up was 3.8 [1.6, 7.1] years. Antibody clearance over time was similar in the three groups with peak anti-HBs ≥100 IU/L, and significantly slower than in the group with anti-HBs <100 IU/L. Peak anti-HBs level was the variable with the greatest impact on anti-HBs clearance in the multivariable analysis. Compared with participants with anti-HBs <100 IU/L, having peak anti-HBs values of 100-499 IU/L, 500-999 IU/L and ≥1000 IU/L were protective factors for anti-HBs clearance, with hazard ratios of .26 [0.23, 0.30], 0.17 [0.13, 0.22] and 0.10 [0.07, 0.12], respectively, Conclusions: Peak anti-HBs level is the key factor of antibody persistence in PWH. Those with anti-HBs levels below 100 IU/L should be monitored closely and considered for a booster dose.
