Percutaneous transluminal renal angioplasty of global kidney ischemia improves renal function and blood pressure.
Article in International journal of cardiology. Heart & vasculature, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundRenal artery stenosis (RAS) can lead to hypertension and renal failure. Nevertheless, its treatment by percutaneous transluminal renal angioplasty (PTRA) remains controversial. It is unknown, whether patients with global kidney ischemia (GKI), that means patients with bilateral RAS or RAS with a single functioning kidney, may benefit from PTRA or not.
methodsWe retrospectively analyzed 93 patients with RAS (25 bilateral or single functioning kidney) undergoing PTRA. Patients had refractory hypertension (≥3 medications). Blood pressure, antihypertensive drugs and serum-creatinine were compared pre-/post-intervention and at 1 year's follow-up.
resultsAt 1 year after PTRA of patients with GKI, systolic and diastolic blood pressure were significantly reduced compared to patients with unilateral PTRA (systolic: -19.1 ± 10.5 [bilateral] vs. -11.4 ± 12.1 mmHg [unilateral], P < 0.01; diastolic: -10.1 ± 6.8 mmHg vs. -6.3 ± 6.6 mmHg, P < 0.05). The number of antihypertensive drugs was reduced by -0.8 ± 3.0 at 1 year in patients with GKI, while it increased by +0.1 ± 3.5 in the unilateral RAS group (P < 0.001). Furthermore, post-interventional serum-creatinine decreased by -34.6 ± 31.4 μmol/I after of patients with GKI (P < 0.001 vs. baseline). In patients with unilateral PTRA, a non-significant increase in serum-creatinine was observed (+8.3 ± 2 μmol/l).
conclusionPTRA in patients with GKI led to improved blood pressure and renal function. A large, well-designed, randomized clinical trial targeting this population is still needed. The benefit of PTRA should be measured with the risks in each patient individually.
