Renal denervation plus cardiac ablation vs. cardiac ablation alone for patients with atrial fibrillation and uncontrolled arterial hypertension : A systematic review and updated meta-analysis of randomized controlled trials.

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
backgroundAtrial fibrillation (AF) is a complex arrhythmia often worsened by hypertension (HTN). Pharmacological treatments frequently underperform, and the best approach, particularly combining renal denervation (RDN) with cardiac ablation (CA), remains unclear.
objectiveWe conducted an updated meta-analysis of randomized controlled trials (RCTs) to evaluate the efficacy of RDN combined with CA versus CA alone in patients with AF and uncontrolled HTN.
methodsWe performed a systematic review and meta-analysis of RCTs retrieved from PubMed, Embase, and the Cochrane Library up to July 2024. Primary outcomes included AF recurrence, periprocedural complications, blood pressure changes, and estimated glomerular filtration rate (eGFR). Risk ratios (RRs) and mean differences (MDs) with 95% confidence intervals (CIs) were computed using a random-effects model.
resultsEight RCTs were included, involving 689 patients (37% female). Of these, 355 underwent RDN + CA, and 334 underwent CA alone, with a mean follow-up of at least 12 months. The RDN + CA group exhibited a significant reduction in AF recurrence (RR: 0.77; 95% CI: 0.61-0.97). There were no significant differences in periprocedural complications (RR: 1.06; 95% CI: 0.60-1.89), systolic blood pressure (MD: -6.79; 95% CI: -14.71-1.14), diastolic blood pressure (MD: -2.47; 95% CI: -8.13-3.20), or eGFR (MD: 1.14; 95% CI: -11.95-14.23).
conclusionOur findings show that RDN combined with CA significantly reduces AF recurrence compared to CA alone, presenting a promising approach for patients with resistant HTN and AF.
