Chronic heart failure and hypoalbuminemia are risk factors of poorer mRNA SARS-CoV-2 vaccine response in maintenance Hemodialysis patients (the COVaccinDia study).

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
backgroundChronic kidney disease represents an immunocompromising condition and a cause of a lower vaccine efficacy, even in patients undergoing maintenance dialysis. Recent SARS-CoV-2 outbreaks have prompted clinicians to better understand the underlying mechanisms and establish more suitable vaccination schedules.
methodsIn a single-center, retrospective, observational study of patients undergoing maintenance dialysis in France, we studied the factors associated with the intensity of the humoral response to a SARS-CoV-2 vaccine in this population, including specific dialysis-related variables.
resultsAfter having received three doses of SARS-CoV-2 mRNA vaccine, a cohort of 80 patients was divided into low-responders (28 patients with an anti-SARS-CoV-2 antibody level of 50-1830 AU/mL) and responders (52 patients with an antibody level > 1830 AU/mL). We found that chronic heart failure (p < 0.00001), higher performance status (p = 0.004), hypoalbuminemia (p < 0.001), lymphopenia (p = 0.003), Rhesus status positivity (p = 0.02), and absence of response to a hepatitis B virus vaccine (p = 0.02) were associated with a poor response to a third dose of SARS-CoV-2 vaccine. In contrast, none of the dialysis-related variables were associated with the vaccine response. In multivariate logistic regression, chronic heart failure (p < 0.0001) and hypoalbuminemia (p = 0.0004) remained associated with a lower humoral response to SARS-CoV-2 vaccine.
conclusionsOur results showed that chronic heart failure and hypoalbuminemia were factors associated with a poor humoral response after three doses of SARS-CoV-2 vaccine. However, we found no association between specific dialysis-related variables and the anti-SARS-CoV-2 antibody titer.
