1 · What the graph read from it

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.

2 · The registry

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

backgroundPhysiologic pacing is increasingly used as an alternative when there is a failure in cardiac resynchronization therapy, with more challenging situations expected consequently. CASE PRESENTATION: An 83 year-old Caucasian man underwent attempted cardiac resynchronization therapy, but was found to have a persistent left superior vena cava and absence of a right superior vena cava. In addition, no suitable coronary sinus veins were found. Instead, conduction system pacing with a modified approach was used.

conclusionThe presence of left superior vena cava is compatible with safe implantation of conduction system pacing, using conventional tools and with mild modification of typical technique.
