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

backgroundKidney transplantation in older adults is expanding, but detailed data on infection burden, antibiotic resistance, and sex-specific outcomes remain limited. The aim of the present study was to characterize infection dynamics and determinants of adverse events in recipients aged ≥ 65 years.

methodsIn this multicenter cohort study, 355 kidney transplant recipients aged 65-80 years (67.6% male) were followed for a median of 3.8 years. Cumulative incidences of infection, graft loss, and death were determined. Independent risk factors were identified using Cox regression analyses.

resultsDelayed graft function occurred in 23.9%, S-creatinine was 1.72 IQR (1.40-2.45) and eGFR 38.7 (26.2-51.3) one year after transplantation. All-cause mortality was 3.2% at year 1 and 11.8% at year 5 after transplantation. Infectious complications were frequent, with a cumulative incidence of first infection reaching 67.6% at 1 year and 81.9% at 5 years. Bacterial infections predominated, whereas viral infections persisted throughout follow-up and fungal infections occurred mainly in the early post-transplant period. During follow-up, death with a functioning graft (DWFG) was the predominant graft-related endpoint, accounting for 35 of 48 all-cause graft loss events, with infections representing the leading attributed cause (51.4%). In multivariable analyses, prolonged initial hospital stay was consistently associated with infectious outcomes and subsequent DWFG, while delayed graft function was independently associated with increased hazard of DWFG (HR 2.54, 95% CI 1.29-5.00). In time-dependent analyses, fungal infections were independently associated with a higher subsequent hazard of DWFG (HR 2.67, 95% CI 1.23-5.77). Mortality, graft-related outcomes, and infection rates were broadly similar by sex and between recipients aged 65-69 and ≥ 70 years.

conclusionsKidney transplantation in carefully selected older recipients, including those aged ≥ 70 years, was associated with sustained patient and graft survival. Infectious complications occurred frequently and constituted the leading attributed cause of DWFG; this underscores the importance of understanding why some recipients recover from infectious stress, while others experience subsequent clinical deterioration.
