Patent foramen ovale closure or medical therapy for secondary prevention of cryptogenic stroke: An update meta-analysis of randomized controlled trials.
Synthesis in Medicine, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundIt was under debate whether cryptogenic stroke patients benefited from patent foramen ovale (PFO) closure. We sought to determine secondary prevention strategy in these patients.
methodsScientific databases were searched for randomized controlled trials enrolling cryptogenic stroke patients with PFO who underwent PFO closure or medical therapy. The random-effect model was used to analyze the outcomes.
resultsWe identified 6 trials enrolling 3630 participants in this meta-analysis. When compared with medical therapy, PFO closure reduced risks of recurrent stroke (risk ratio [RR] 0.52, 95% confidence interval [CI] 0.29-0.93) and composite of stroke and transient ischemic attack (TIA) (RR 0.60, 95% CI 0.46-0.80). And no differences in all-cause death (RR 0.80, 95% CI 0.37-1.72) and cardiovascular death (RR 1.47, 95% CI 0.36-5.94) between 2 groups were observed. The risks of major bleeding (RR 0.96, 95% CI 0.47-1.96) and any serious adverse event (RR 1.03, 95% CI 0.92-1.16) did not differ between 2 groups. Yet, PFO closure increased risk of atrial fibrillation (RR 4.25, 95% CI 2.10-8.60).
conclusionPFO closure, as compared with medical therapy, was associated with decreased risk of recurrent stroke and increased risk of atrial fibrillation in cryptogenic stroke patients with PFO.
