A novel therapy for eliminating phrenic nerve stimulation: a long-term follow-up case report.
Article in Frontiers in cardiovascular medicine, 2026. 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
Phrenic nerve stimulation (PNS) is a frequent occurrence in patients implanted with a cardiac resynchronization therapy (CRT) device. Most PNS can be eliminated by external programming of pacing threshold, pacing polarity, etc., but there are still a small number of refractory PNS cases that need electrode reset. The latter has many uncertainties, such as poor coronary sinus (CS) target vessel conditions, venous pathway obstruction or occlusion, recurrence of PNS, pacemaker sac infection, disappearance of CRT super response, etc. In view of this, we reported one case of PNS after CRT treated by isolating the left phrenic nerve (PN) and the left ventricular (LV) electrode.
