Serum titer of neutralizing antibodies after COVID-19 vaccination in Japanese patients with inflammatory bowel disease.
Article in Journal of clinical biochemistry and nutrition, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Vaccination is an important strategy to reduce the infection rate and adverse events of coronavirus disease 2019 (COVID-19). However, the effect of COVID-19 vaccination for Japanese patients with inflammatory bowel disease (IBD) has not been fully elucidated. In the present study, we investigated the serum titer of neutralizing antibodies after COVID-19 vaccination in patients with IBD, treated with and without immunosuppressive therapy. The study consisted of 108 patients with IBD [76 with ulcerative colitis (UC) and 32 with Crohn's disease (CD)] from the gastroenterology outpatient clinic at the Hospital of the Kyoto Prefectural University of Medicine who underwent anti-severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccination. The control group included 64 healthy subjects who received the anti-SARS-CoV-2 vaccine. When 10 AU/ml of neutralizing antibodies was used as cut-off value, the positive rates of neutralizing antibodies of patients with UC, patients with DC, and the control group were 97.3%, 84.3%, and 100%, respectively. The neutralizing antibody titer showed no difference between patients treated with and without immunosuppressive therapy. These results indicate that COVID-19 vaccination may be useful in patients with IBD, treated with or without immunosuppressive therapy.
