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

backgroundCardiovascular diseases are still highly prevalent after kidney transplantation. However, little is known about the impact of the timing of rejection episodes on cardiovascular disease. The study aimed to analyze the influence of the timing of rejection episodes on cardiovascular events in recipients of living donor kidney transplantation.

methodsWe studied 572 living donor kidney transplant recipients from the Michinoku Renal Transplant Network (MRTN), which includes 6 centers in the Tohoku region of Japan. Fine-Gray proportional hazards regression analysis with time-dependent variables was used to assess the effect of rejection episode on cardiovascular events. Recipients were divided into three groups: those without rejection (non-rejection, 370 patients), rejection within 6 months after transplantation (early rejection, 99 patients), and rejection after 6 months (late rejection, 103 patients). The effect of timing on cardiovascular events was evaluated using Fine-Gray proportional hazards regression analysis.

resultsDuring a median follow-up of 77 months, 70 patients experienced cardiovascular events. Rejection episodes were significantly associated with cardiovascular events (hazard ratio [HR]: 2.08, 95% confidence interval [CI]: 1.26-3.43, P = 0.004), along with age and dialysis vintage. The 5-year cumulative incidence of cardiovascular events was significantly higher in the late rejection group than in the early rejection group (15% vs. 3.3%, P = 0.021). However, no significant difference in 5-year cumulative cardiovascular event incidence was observed between the early rejection and non-rejection groups. Late rejection was significantly associated with cardiovascular events (HR: 2.40, 95% CI: 1.38-4.18, P = 0.002), whereas early rejection was not significantly correlated with cardiovascular event risk (HR: 1.18, P = 0.670).

conclusionsRejections occurring more than 6 months after transplantation is significantly associated with risk of cardiovascular events. TRIAL REGISTRATION NUMBER: 2019-099-1, date of registration; 3 Dec. 2019, retrospectively registered.
