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
backgroundImmunosuppressed kidney transplant patients may have suboptimal response to vaccinations. The aim of this study was to determine antibody response to a quadrivalent meningococcal conjugate vaccine (MenACWY-D) in adolescents with a kidney transplant.
methodsThis was a prospective, single-center, cohort study. Adolescent patients (11-22 years old) with a functioning kidney transplant for at least 3 months and no previous meningococcal vaccination were eligible for enrollment. Antibody levels to all serogroups were measured before vaccination (baseline) and at 4 weeks and 1, 2 and 3 years after vaccination. Seropositivity was defined as a titer ≥ 1:8 at baseline, and seroconversion as a fourfold or greater increase in antibody titer from baseline at 4 weeks post-vaccination. Geometric mean titers (GMTs) were calculated at each time point and compared to published GMTs from vaccinated healthy adolescents.
resultsNineteen patients were enrolled. No patient had seroprotective titers against all four serogroups at baseline. At 4 weeks post-vaccination 41% of patients seroconverted to all four serogroups, with seroconversion rates of 88, 53, 71 and 94% for serogroups A, C, W and Y, respectively. GMTs were significantly lower in adolescents with a kidney transplant than in healthy adolescents at 1 month (p = 0.02) and 3 years (p = 0.04) post-vaccination. There were no significant adverse events, episodes of rejection or death in any patient.
conclusionsAdolescents with a kidney transplant may not respond adequately to MenACWY-D and may experience more rapid declines in antibody titers than healthy adolescents. Further study is needed to determine if alternative dosing schedules can improve antibody response in this population.
