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

purposeThis study evaluated the short-term efficacy and safety of prostatic artery embolization (PAE) using ethylene vinyl alcohol copolymer (EVOH) for symptomatic benign prostatic hyperplasia (BPH) and investigated the impact of EVOH penetration on clinical success. MATERIALS AND

methodsThis retrospective, single-center study analyzed 73 men who underwent EVOH-based PAE. The primary endpoint was 3-month clinical success, defined as an International Prostate Symptom Score (IPSS) < 18 with a ≥ 25% decrease and an IPSS-related QoL score ≤ 3 with ≥ 1-point decrease. Complications were graded according to the Clavien-Dindo and CIRSE classification systems. Final cone-beam CT (CBCT) was performed to identify non-target embolizations (NTEs) and to grade EVOH penetration into each hemiprostate using a 0-3 scale. The Prostatic EVOH Penetration Score (PEPS) categorized whole-prostatic embolization as high (3|3, 3|2), medium (3|1, 2|2), and low (others). The secondary objective was to assess the correlation between PEPS groups and clinical success.

resultsThree-month clinical success was 88% (64/73), with a median IPSS decrease of - 12 points (Q1, Q3: - 17, - 7; P < 0.001) and a median QoL decrease of - 3 points (Q1, Q3: - 4, - 2; P < 0.001). No major complications occurred; 12/73 (16%) patients experienced minor complications. Eight NTEs were identified in 7/73 (10%) patients, all asymptomatic. Clinical success occurred in all patients with high PEPS (n = 57), in 7/11 (64%) patients with medium PEPS, and in none with low PEPS (n = 5) (P < 0.001).

conclusionEVOH-based PAE is safe and effective at 3 months for BPH-related symptoms. PEPS may help better define technical success as a predictor of short-term clinical outcomes.
