Humoral response to SARS-CoV-2 after vaccination and booster effect in patients undergoing dialysis.

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
objectiveThe aim of this study was to determine and evaluate the postvaccination variation in immunoglobulin G (IgG) receptor-binding domain (RBD) produced in non-SARS-CoV-2-infected patients with nephropathy and renal replacement therapy.
methodsThis is a follow-up study of the humoral response to the BNT162b2 messenger ribonucleic acid COVID-19 vaccine in patients with nephropathy, comparing it with itself at different times and with the healthy population.
resultsIn patients with nephropathy, a very striking decrease in IgG RBD was observed compared with the healthy population (P<0.001) at three months after the second dose. In patients with nephropathy, the response rate ≥590 binding antibody units/ml (4154 AU/ml) was detected in 45% of patients, 15 days after the second dose, whereas at 3 months, this decreased to 9% (P<0.05) and then increased to 86% after the third dose (P<0.001).
conclusionIn patients with nephropathy and renal replacement therapy, it is necessary to administer a third-dose vaccination within 3 months after the second dose. It is important to continue monitoring the humoral response to obtain a better SARS-CoV-2 vaccination schedule.
