First And Second-Generation Cryoballoon Ablation Efficacy Restoring And Maintaining Sinus Rhythm In Patients Electrically Selected And Treated For Long-Standing Persistent Atrial Fibrillation After Acute Complete Electrical Disconnection Of Pulmonary Veins From The Left Atrium Demonstrated.
Article in Journal of atrial fibrillation. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Introduction Cryoballoon ablation (CB) has proven effective to treatment of patients (pts) with atrial fibrillation (AF). However, the isolated efficacy of CB to treat pts with long-standing persistent atrial fibrillation (LSPAF) is less know. We analyzed the acute results and the long-term follow-up of our pts suffering LSPAF and initially treated with CB. Methods A cohort of 44 pts, 37 male (84%) mean age (60±10 year) suffering LSPAF were treated with first (CB1): 15pts, and second (CB2): 29 pts, generation CB. Eight pts (18.1%) had structural heart disease. Prior to CB, all pts were previously electrically cardioverted (CV) and sinus node and A-V nodal function evaluated at electrophysiological study (EP) once in sinus rhythm (SR) before antiarrhythmic drugs (AAD) load. CB ablation procedure was performed after three months waiting period on AAD following CV/EP drug testing. Result CB procedure was performed in 27 (61.4%) in AF, restoring SR in 8 (18.2%). PV isolation (PVI) was achieved in 95.2%. On follow-up of 30±39 months, 16 pts (40%) had AF recurrence. Second procedure (Redo) was performed in 7 pts. After a single procedure, 24 pts (60%) remain in SR without AAD, after Redo, 29 pts (72.5%), and when AAD added, 31 pts (77.5%) remain in SR. Phrenic nerve palsy (PNP) occurred in 9% of pts (75% with CB2). Conclusion CB technique is safe and useful tool to treat pts with LSPAF with 60% success rate maintaining SR without AAD in a long-term follow-up (30±39 months), up to 72.5% after Redo, and to 77.5% when AAD are added. In the majority of pts maintaining SR (77.5%) CB2 was used in 87% of the cases. Patients without structural heart disease along with those who SR was restored during CB showed the best result.
