Is the time of atrial fibrillation recurrence after cryoballoon ablation of paroxysmal atrial fibrillation influenced by the pattern of PV reconnections?

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
backgroundPulmonary vein isolation (PVI) with 2nd-generation cryoballoon (CB) has been shown to be effective in the treatment of paroxysmal atrial fibrillation (AF). We describe pulmonary vein (PV) reconnection at repeat ablation in patients with AF recurrence after CB PVI and analyze the correlation between the time of AF recurrence and the observed PV reconnection patterns.
methodsSixty-six patients undergoing a redo PVI for recurrent AF were enrolled 9.1 ± 2.6 months after the initial CB PVI procedure.
resultsNinety-two percent had PV reconnections with a mean of 1.97 ± 0.8 reconnected PVs/patient, and 52% of formerly isolated PVs were found reconnected. The highest reconnected rates were observed for left superior PVs (67%). Fifty-three percent of the patients had 2 reconnected PVs, no patient had all PVs reconnected, and 8% were without PV reconnection. There was a significant negative correlation between the time of AF recurrences and the extent of PV reconnections at redo PVI for patients with proven PV reconnection in more than one PV (R = 0.52, p < 0.001), while all patients without PV reconnection had AF recurrences within the first 9 months after PVI.
conclusionsAt redo ablation, most patients with recurrence of AF after CB PVI had PV reconnection(s). Patients with PV reconnection(s) showed a negative correlation between the number of reconnected PVs and the time of AF recurrence with more extensive PV reconnections resulting in earlier PV recurrences after the blanking period. Patients without PV reconnection experienced early AF recurrences, indicating non-PV triggers contributing for paroxysmal AF recurrences in these patients.
