Interactive effect of booster vaccination and vitamin D status on antibody production of Omicron variant-infected adults: A real-world cohort study.
Article in The clinical respiratory journal, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
introductionEffect of booster vaccination and vitamin D status on antibody production of Omicron variant-infected adults need to be further explored.
methodsA retrospective, longitudinal, real-world cohort study was performed. All included cases were divided into vitamin D deficiency (VDD) and non-VDD (control) groups according to baseline serum 25-hydroxyvitamin D [25(OH)D] concentration and then into unvaccinated, routinely vaccinated, and booster vaccinated VDD and control subgroups according to vaccination status. Antibody dynamics were observed within six time periods during hospitalization.
resultsA total of 204 adult cases were included, of which 121 (59%) were males; 23 (11%), 31 (15%), and 26 (13%) or 50 (25%), 35 (17%), and 39 (19%) were unvaccinated, routinely vaccinated, and booster vaccinated VDD cases or controls, respectively. The median (interquartile range) for age and baseline 25(OH)D concentration was 42.5 (31-53.5) years and 21.5 (18-25.4) ng/mL, respectively. The IgM titers within 3 to 7 days and 7 to 14 days increased rapidly to 1.8-fold (P < 0.001) and 3.6-fold (P < 0.001) those within the first day; the IgG titers increased to 5.8-fold (P < 0.001) and 10.9-fold (P < 0.001). Booster vaccinated controls had higher first IgG titers compared with unvaccinated controls (3.1-fold; P = 0.001) or booster vaccinated VDD cases (2.1-fold; P = 0.02).
conclusionsBooster vaccination and non-VDD status may have an interactive boosting effect on IgG production of Omicron variant-infected adults. Further randomized clinical trials may be needed to determine whether booster vaccination combined with VDD correction improves the humoral immunity to Omicron variants.
