1 · What the graph read from it

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.

2 · The registry

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

backgroundIn the general population, mRNA SARS-CoV-2 vaccines are highly efficacious. Early reports suggest a diminished antibody response in immunosuppressed adult solid organ transplant (SOT) patients, but this has not been reported in pediatrics.

methodsAdolescent kidney transplant recipients (KTR) at our center who received both doses of an mRNA SARS-CoV-2 vaccine had SARS-CoV-2 spike (S) protein antibody presence evaluated 4-8 weeks after their second dose of the vaccine as part of routine clinical care.

resultsThirteen of 25 fully vaccinated patients (52%) had a positive spike antibody. Median age of participants was 19 years old (IQR 18-20) and the median time from transplant was 5 years (IQR 4-9 years). KTR were treated with an immunosuppression regimen including a calcineurin inhibitor, corticosteroid, and antimetabolite (9 with mycophenolate, 3 with azathioprine, and 1 without an antimetabolite due to viremia). Of those who had an antibody response, fewer had a mycophenolate-containing immunosuppressant regimen than non-responders. There was a trend toward better vaccine response and higher anti-S antibody titers at lower doses of mycophenolate. Three patients with prior COVID-19 infection all had a positive antibody response.

conclusionOur results suggest vaccine response in adolescent KRT is lower than that of the general population, but similar to that previously described in adult SOT patients and slightly better than that seen in adult KTR. This data demonstrates vaccination is safe and supports immunizing KTR who remain hesitant. Future studies should focus on better understanding of the cellular immune response to vaccination and strategies to enhance vaccine immunogenicity in pediatric SOT patients.
