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

Background: Brugada syndrome (BrS) is a rare cardiovascular condition that can lead to life-threatening arrhythmias. The Case summary: We describe a case series of three unrelated patients who underwent an exercise treadmill test (ETT) according to standard Bruce protocol. Each patient demonstrated a Type 1 Brugada pattern most apparent in the early recovery phase immediately after peak exercise but not at baseline. Discussion: This case series highlights the value of ETT as a diagnostic aid for BrS. We suggest that ETT could be considered as a routine means of provoking a Brugada ECG pattern.
