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

Thrombotic thrombocytopenic purpura (TTP) affects essentially all organ systems. Myocardial injury in TTP is often attributed to microthrombi formation. We present the first case report in the literature of an acute TTP patient with concomitant obstructive coronary artery disease (CAD) and acute myocardial infarction who underwent successful percutaneous coronary intervention (PCI). A 70-year-old female patient who was diagnosed with acute TTP required plasma exchange. The patient also experienced episodes of angina pectoris, elevated cardiac enzymes and global ST segment depressions on ECG. A subsequent non-invasive ischaemia workup revealed significant ischaemia. Coronary angiography revealed obstructive CAD in her right coronary artery, requiring PCI with a bare metal stent placement and dual antiplatelet therapy. The patient tolerated antiplatelet therapy well. At 6 months of follow-up, she had no recurrent angina. This case highlights the potential co-existence of obstructive CAD and acute TTP requiring careful differential diagnosis and treatment.
