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

A rise and/or fall in troponin level is an indication of type 1 or 2 myocardial infarct. A 62-year-old male physician presented to emergency room with chest discomfort followed by thought to be normal electrocardiogram (ECG) and normal echocardiography results. His serial hs-troponin test showed remarkable escalation three hours from the initial (107 ng/l into 4.978 ng/l), suggesting a high-risk non-ST-segment myocardial infarction (NSTEMI). An early invasive procedure was performed, showing acute total occlusion (TO) in the obtuse marginal 1 branch. We retrospectively reviewed our examination to diagnose better the presence of TO in NSTEMI patients presented with non-diagnostic examination. Our evaluation showed a minor change in the form of an 'N-wave' pattern on the ECG, which was not yet an established guideline criterion for prompt angiography. Although ECG pattern is often normal in LCx occlusion, recent study shows the presence of 'N-wave' ECG pattern in 10% of NSTEMI cases following TO at LCx.
