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 and Aims: Our aim was to determine the immune efficacy of a severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) booster vaccination in cirrhotic patients who had received the primary series. Methods: We performed a longitudinal assessment in 48 patients with cirrhosis, 57 patients with chronic hepatitis B (CHB) and 68 healthy controls (HCs) to continuously track the dynamics of SARS-CoV-2 specific antibodies and memory B cells after receiving the primary series and booster dose at different times. A pseudovirus neutralization assay was used to determine neutralization against Omicron subvariants BA.2.12.1, BA.4 and BA.5 from serum samples collected from three cohorts. Results: Serum anti-receptor-binding domain (RBD) immunoglobulin (Ig)G and neutralizing antibody (NAb) levels in cirrhotic patients were elevated within 15-45 days after completing the primary series before rapidly declining and reaching a valley at around 165-195 days. After receiving the booster dose, both antibody levels were significantly increased to levels comparable to patients with CHB and HCs. Subgroup analysis showed that booster vaccination induced weaker antibody responses in patients with decompensated cirrhosis than in those with compensated cirrhosis. The SARS-CoV-2 memory B-cell response in cirrhotic patients was durable during follow-up regardless of the hepatic fibro-cirrhosis grade. However, compared with the primary series, the booster dose did not result in an evident improvement of neutralization activity against the Omicron subvariants BA.2.12.1 and BA.4, and was followed by a significant decrease in the titer against BA.5. Conclusions: A booster dose elicited a robust and durable humoral response to the wild-type strain in cirrhotic patients but not the Omicron subvariants. Repeated vaccination of inactivated SARS-CoV-2 vaccine may not benefit cirrhotic patients in neutralization against newly circulating strains.
