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
backgroundThe aim of the present study is to evaluate the short-term efficacy and feasibility of radiofrequency ablation in the treatment of complex diffuse arteriovenous (AV) malformations.
methodsThe data of 18 patients (8 male and 10 female) with complex AV malformations treated between December 2014 and June 2019 were analyzed retrospectively. The lesion area was 10 × 7 cm ~ 28 × 30 cm. Under duplex ultrasound guidance, the site with the most abundant blood flow signals in the lesion was percutaneously punctured with the radiofrequency ablation needle (electrode). The impedance automatic adjustment mode was adopted, and ablation was monitored usingduplex ultrasoundduring the entire process.
resultsOf the included patients, 1 had a high fever after two rounds of treatment, 2 had transient hemoglobinuria, and 1 had tissue necrosis in the original ruptured tumor area as well as a penetrating defect in the cheek, which was repaired with a pedicled trapezius myocutaneous flap. In 9 patients who experienced bleeding, the bleeding stopped after one round of treatment. During the follow-up period of 1-5 years, there were 0 grade I (poor) cases, 0 grade II (medium) cases, 7 grade III (good) cases, and 11 grade IV (excellent) cases.
conclusionThe "high power and continuous" radiofrequency ablation technique conducted under real-time duplex ultrasoundmonitoring can completely destroy the deep core lesions of AV malformations and effectively control life-threatening massive hemorrhage; it is an effective alternative treatment method for complex diffuse AV malformations in which interventional embolization, sclerotherapy, and surgery are ineffective.
