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

Sympathetic dysfunction is characterized by postural hypotension, decreasing blood pressure without compensatory tachycardia during graded supine ergometric exercise, impaired catecholamine metabolism, and hypersensitivity to catecholamines. We report on eight patients, seven with sympathetic dysfunction, of whom three patients were treated for the first time with programmed subcutaneous noradrenaline administration by means of a microdosing pump over a time period of 1.5-13 months. A clear improvement in blood pressure values, orthostasis tolerance, and exercise capacity has been observed in these three patients which permit them to extend their action radius. Adjustment of the noradrenaline dose to the wide range of everyday stress and the possible occurrence of adrenoreceptor desensitization, however, remains a severe problem.
