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

Wellens' syndrome is an electrocardiographic pattern of T-wave changes associated with critical stenosis of the proximal left anterior descending artery, signifying imminent risk of an anterior-wall myocardial infarction. The Wellens' electrocardiographic pattern can also be noted in several cardiac and non-cardiac diseases. We chronicle here a unique case of a patient who presented with atypical left chest pain and dizziness for 6 hours. His pain started after he smoked phencyclidine-laced cannabis. Cardiac panel demonstrated normal troponin T levels. Electrocardiogram showed sinus rhythm with new deep biphasic T-wave inversions in anterolateral leads. Coronary angiography showed no pathological processes. Subsequently, ECG changes resolved coincidentally with the resolution of chest pain. He was eventually diagnosed with pseudo-Wellens' syndrome. This paper illustrates that physicians should be vigilant for Wellens' syndrome mimicked by acute phencyclidine and cannabis intoxication. Additionally, we present a review of various aetiologies of pseudo-Wellens' syndrome, especially in patients with substance abuse.
