Clinical characteristics, diagnostic modalities, and therapeutic strategies of spontaneous renal artery dissection: A systematic review and diagnostic analysis.
Synthesis in PloS one, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectiveTo investigate the clinical features, diagnostic approaches, and treatment strategies of spontaneous renal artery dissection (SRAD) through systematic review and data analysis, thereby providing evidence-based insights for optimizing clinical management.
methodsA systematic search was conducted across PubMed, Embase, Cochrane Library, Web of Science, China National Knowledge Infrastructure (CNKI), and Wanfang Database. Case-control studies, cohort studies, and case series were included. Demographic data, symptomatology, diagnostic modalities, treatment regimens, and clinical outcomes were extracted. Statistical analyses were performed using RStudio.
resultsA total of 73 case reports involving 97 patients were included. The mean patient age was 46 years, with a male predominance (82.5%, 80/97). The most common presenting symptom was acute-onset flank pain (74.2%), and comorbid hypertension was observed in 61.9% of cases. Computed tomography angiography (CTA) was the primary diagnostic modality (85.6%), with multimodal imaging utilized in 87.6% of cases. Revascularization rates differed significantly between conservative management (37.1%), endovascular intervention (71.0%), and surgical intervention (6.2%) (P < 0.01). Regarding blood pressure outcomes: the proportion of patients achieving normotension without medication was significantly higher in the non-conservative group (54.1%, 20/37) than in the conservative group (30.0%, 6/20) (P < 0.05); however, there was no statistically significant disparity in the overall blood pressure control rate (normotension without medication + controlled with medication) between groups (P > 0.05). Overall mortality was 3.1%, and renal function deterioration occurred in 30.9% of patients.
conclusionManagement of SRAD necessitates individualized decision-making. Conservative therapy remains appropriate for most patients, while endovascular intervention demonstrates superior revascularization efficacy in cases with severe symptomatology or dissection progression. Prospective studies are warranted to validate therapeutic disparities and establish standardized diagnostic and treatment protocols.
