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
Hypertension is a major risk factors for stroke, cardiovascular diseases, and chronic kidney diseases. Although taking antihypertension drugs improves the prognosis of hypertensive patients to a certain extent, there are still lots of refractory hypertension and non-adherent patients. Therefore, it is imperative to explore more effective and targeted treatment approaches. Herein, we construct a multifunctional photothermal hydrogel to treat hypertension and cardiac remodeling through renal denervation (RDN) under 808 nm near-infrared (NIR) laser irradiation. The prepared multifunctional hydrogel, which is customized based on renal perivascular microenvironment, exhibits excellent stretchability, mechanical properties, flexibility and adhesion, ensuring it with remarkable conformability to the dynamic movements of the renal arteries throughout RDN procedures. Photothermal RDN achieved significant blood pressure reduction, with sustained decreases of 13.3 ± 2.5 mmHg in systolic blood pressure and 10.6 ± 1.2 mmHg in diastolic blood pressure, persisting for 8 weeks post-treatment. Additionally, a reduction in myocardial fibrosis and cardiomyocyte hypertrophy is observed, which indicative of the alleviation of cardiac remodeling. The antihypertensive effect of photothermal RDN is mediated through inhibition of the renin-angiotensin-aldosterone system (RAAS) pathway and activation of the cGMP-PKG signaling cascade. The photothermal hydrogel-mediated RDN treatment provides a promising and innovative strategy for treating hypertension and cardiac remodeling.
