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
backgroundGanglionated plexi (GP) ablation may be associated with improved syncope or arrhythmia-free survival arrhythmia patients with vasovagal syncope (VVS) and atrial fibrillation (AF), respectively. We aimed to compare the characteristics of vagal response (VR) and clarify the effect on heart rate after GP ablation based on clinical diagnosis.
methodsA total of 83 consecutive patients undergoing GP ablation were divided following two groups: (1) GP ablation for VVS (VVS group, n = 43) and (2) GP ablation in addition to pulmonary vein isolation (AF group, n = 40). We examined VR characteristics during RF ablation and high frequency stimulation, respectively, in the VVS and AF groups. To evaluate immediate and long-term heart rate response, a standard 12-lead ECG was obtained at baseline at 24 h after ablation and at the last follow-up visit.
resultsIn the VVS group, the superior and inferior left atrial GPs were the most common GP sites at which a VR was observed. No VR was seen during radiofrequency application in the superior and inferior right atrial GPs in the VVS group. On the contrary, VR was more prevalent in the right-sided GPs during high-frequency stimulation in the AF group. VR was observed during ablation in only one patient with AF. Although the heart rate increased significantly after ablation in both groups, the effect was more prominent and durable in the VVS group.
conclusionsThe autonomic response during GP ablation is different in VVS compared to AF, suggesting that VVS and AF may represent distinct forms of autonomic hyperactivity.
