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 postpartum patient with acute-onset dyspnoea and hypotention, associated with reduced left ventricular function requiring intensive blood pressure control, was initially misdiagnosed as having peripartum cardiomyopathy. Her clinical symptoms rapidly resolved. Echocardiography revealed reversible left ventricular dysfunction with apical ballooning and coronary angiography was normal. Based on these findings, we diagnosed takotsubo syndrome. Over the next two months, the patient experienced repeated bouts of elevated sympathetic activity. On workup, we found an adrenal mass and elevated urine metanephrines. After adrenalectomy, histology confirmed pheochromocytoma. Our patient had the rare diagnosis of postpartum pheochromocytoma-induced takotsubo syndrome.
