Predictors of renal outcomes and mortality in patients with renal vein thrombosis: a retrospective multicenter study.
Article in Journal of nephrology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
backgroundStudies on renal vein thrombosis have been conducted as case reports or case series. The renal outcomes and mortality risk of renal vein thrombosis have not been fully established. We aimed to investigate the clinical characteristics, treatment modalities, and predictors of renal outcomes and mortality in patients with renal vein thrombosis in a large multicenter cohort.
methodsWe retrospectively assessed 182 patients with renal vein thrombosis diagnosed between January 2011 and May 2023 using either Doppler ultrasonography or computed tomography venography. The main outcomes analyzed were all-cause mortality, and worsening kidney function.
resultsWe evaluated 182 patients comprising 76 males (41.8%) and 106 females (58.2%). Nephrotic syndrome was the most common cause (51.6%) followed by malignancy (33%) and post-trauma or surgery (11%). Kidney function worsened in 126 patients (69.2%). Acute kidney injury (AKI) was identified in 72 patients (39.6%), whereas 54 patients (29.7%) developed chronic kidney disease (CKD). Multivariate logistic regression showed that declining kidney function was reliably predicted by nephrotic syndrome (Odds ratio (OR): 6.41, P = 0.004), serum albumin (OR: 0.31, P = 0.003), and diabetes mellitus (OR: 14.04, P < 0.001). Eighty-two patients (45.1%) died while being monitored. Sepsis accounted for the majority of deaths (25.3%). Bilateral renal vein thrombosis (Hazard Ratio (HR): 5.61, P < 0.001), malignancy (HR: 6.15, P = 0.004), serum albumin (HR: 0.12, P < 0.001), hemoglobin (Hb) level (HR: 0.102, P < 0.001) and diabetes mellitus (HR: 2.42, P = 0.007) were all reliable predictors of all-cause mortality using multivariate Cox regression.
conclusionRenal vein thrombosis is associated with a higher risk of mortality and worsening kidney function. It is essential to promptly identify high risk patients and start early treatment to prevent unfavorable outcomes.
