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/

aimsData of coronavirus disease 2019 (COVID-19) vaccine immunogenicity among chronic liver disease (CLD) and liver transplant (LT) patients are conflicting. We performed meta-analysis to examine vaccine immunogenicity regarding etiology, cirrhosis status, vaccine platform and type of antibody.

methodsWe collected data via three databases from inception to February 16, 2022, and reported pooled seroconversion rate, T cell response and safety data after two vaccine doses.

resultsTwenty-eight (CLD only: 5; LT only: 18; both: 2; LT with third dose: 3) observational studies of 3,945 patients were included. For CLD patients, seroconversion rate ranged between 84% (95% confidence interval [CI], 76-90%) and 91% (95% CI, 83-95%), based predominantly on neutralizing antibody and anti-spike antibody, respectively. Seroconversion rate was 81% (95% CI, 76-86%) in chronic hepatitis B, 96% (95% CI, 93-97%) in non-alcoholic fatty liver disease, 85% (95% CI, 75-91%) in cirrhosis and 85% (95% CI, 78-90%) in non-cirrhosis, 86% (95% CI, 78-92%) for inactivated vaccine and 89% (95% CI, 71-96%) for mRNA vaccine. The pooled seroconversion rate of anti-spike antibody was 66% (95% CI, 55-75%) after two doses of mRNA vaccines and 88% (95% CI, 58-98%) after third dose among LT recipients. T cell response rate was 65% (95% CI, 30-89%). Prevalence of adverse events was 27% (95% CI, 18-38%) and 63% (95% CI, 39-82%) among CLD and LT groups, respectively.

conclusionCLD patients had good humoral response to COVID-19 vaccine, while LT recipients had lower response.
