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

1. The effect of varying adrenal blood flow on the rate at which it was estimated that adrenocorticotrophin (ACTH) was presented to the adrenal gland was related to right adrenal cortisol output in conscious calves fitted with 'adrenal clamps'. 2. Intra-aortic infusions of endothelin at either 15.0 or 7.5 pmol min-1 kg-1 produced a substantial fall in right adrenal blood flow which was dose-related over this range. There was an associated fall in right adrenal cortisol output and cortisol output was linearly related to estimated ACTH presentation to the gland over the whole range investigated. The changes in adrenal cortisol output were reflected by changes in the concentration of cortisol in the peripheral plasma, which could be attributed entirely to the fluctuations in adrenal cortisol output. 3. It is concluded that delivery of ACTH to the adrenal gland is flow dependent over the physiological range in these animals and that changes in adrenal cortical blood flow can therefore be expected to result in changes in adrenal output due to variations in the presentation rate of ACTH.
