Predictors for transplant renal artery stenosis in kidney transplant recipients: a systematic-review and meta-analysis.
Synthesis in International urology and nephrology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundKidney transplant recipients after kidney transplantation may develop transplant renal artery stenosis (TRAS). Multiple studies have sought to identify risk factors, yet the findings remain inconsistent.
methodsPubMed, Scopus, and Web of Science Core Collection were comprehensively searched to retrieve studies. The 1st screening phase required studies to be in English and evaluate patients with TRAS. The 2nd screening phase needed studies to provide extractable data. Quality of each included study was assessed using the Newcastle-Ottawa Scale. The protocol was registered through PROSPERO (CRD42023455295).
resultsA total of 25 cohort and 6 case-control studies were included, with the majority being of moderate quality. The predictors for TRAS identified in univariate analysis were deceased donor (odds ratio (OR), 1.74; p = 0.04), delayed graft function (OR 2.46; p = 0.0004), acute rejection (OR 2.03; p = 0.001), prolonged cold ischemia time (p = 0.01), multiple renal arteries (OR 1.73; p = 0.03), right kidney implantation (OR 1.89; p = 0.005), ischemic heart disease (OR 1.64; p = 0.0004), diabetes mellitus (OR 1.58; p = 0.001), hypertension (OR 1.28; p = 0.0009), immunosuppression with mycophenolate mofetil (OR 1.22; p = 0.02), cytomegalovirus status (OR 1.94; p 0.0001) and older recipient age (p = 0.01).
conclusionsThis study provides the largest and most reliable review on predictors for TRAS following kidney transplantation. Despite the chance of some factors being dependent of one another, our findings would still be helpful for clinicians in risk-stratification for TRAS and long-term follow-up of kidney transplant recipients.
