Three-Month Magnetic Resonance Imaging Post-Prostate Artery Embolization Predicts 1-Year Clinical Outcomes.
Article in Cardiovascular and interventional radiology, 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
purposeTo investigate whether post-prostate artery embolization (PAE) magnetic resonance imaging (MRI) can predict clinical outcomes at 1 year. MATERIALS AND
methodsRetrospective study of 63 consecutive patients undergoing microsphere PAE for benign prostatic enlargement. Clinical assessments were performed with the International Prostate Symptom Score (IPSS), quality of life (QoL) scores, and non-invasive urodynamics. MRI was performed at baseline and 3-month post-PAE: intravesical protrusion, prostate volume (PV), and infarction volumes were measured with semi-automated volumetry. Clinical success was defined as (1) a reduction of IPSS to < 9 and QoL score to < 3 or (2) freedom from urinary catheter in catheter-dependent patients. Statistical modeling was performed with multivariate logistic regression.
resultsSixty-three patients were included. Median PV 116 ml (IQR 85-153); median PV reduction 26% (IQR 19-45) at 3 months. Presence of infarction on 3-month MRI was associated with clinical success at 12 months (OR = 1.15, 95% CI: 1.04-1.36, p = 0.025). A receiver operator curve analysis of infarct volume returned an area under the curve of 0.77 (CI 0.66-0.89) and indicated that an infarct volume ≥ 5% had a sensitivity of 72% and specificity of 80% to predict clinical success. PV reduction did not show statistically significant correlation with clinical success (p = 0.348, 95% CI: 0.98-1.08). A lower baseline IPSS was correlated with better clinical outcomes (OR 0.78; 95% CI 0.64-0.91; p = 0.003). Other clinical and anatomical variables including intravesical protrusion were not correlated with clinical outcomes.
conclusionLower baseline IPSS and presence of infarction of > 5% on 3-month post-PAE MRI were associated with better clinical outcomes at 12 months.
