Impact of immunosuppressive regimens on antibody response after COVID-19 vaccination among Thai kidney transplant recipients.

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
Background: The lower humoral immunity response after the COVID-19 vaccine in kidney transplant recipients (KTR) has been reported in several studies. However, there are few studies on the efficacy of the ChAdOx1 nCoV-19 (AstraZeneca) vaccine compared between various immunosuppressive regimens. Methods: We conducted a prospective cohort study at Siriraj Hospital, Bangkok, Thailand. Adult KTRs who received two doses of the ChAdOx1 nCoV-19 vaccine at intervals of 3 months were enrolled. Anti-SARS-COV-2 S-RBD-IgG antibody (anti-RBD) was assessed at the one month after the second dose and considered positive if the level ≥50 AU/mL or 7 BAU/mL. The primary outcome was the seropositivity of anti-RBD. The association between type, dose, and level of immunosuppressive regimen and anti-RBD seropositivity was analyzed. Results: Between October 2021 and January 2022, 139 KTRs with a median time of 55 months (IQR, 29-102 months), were enrolled. The mean age was 49.1 ± 11.3 years and 64.7 % were men. Seroconversion of anti-RBD was found in 72 patients (51.8 %). The seropositive rate was significantly higher in KTR who received tacrolimus (TAC)/everolimus (EVR)/prednisolone (CS) immunosuppression than EVR/mycophenolic acid (MPA)/CS and TAC/MPA/CS, respectively (95 % vs. 65 % vs. 34 %; Conclusion: The anti-RBD response after ChAdOx1 nCoV-19 vaccination was revealed in 51.8 % of the KTR. KTRs who received the TAC/EVR/CS regimen had the highest immune response after vaccination, relatively comparable to the general population. The immunosuppressive regimen should be considered for a further vaccine dose in KTR.
