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

Primary hyperparathyroidism (PHPT) may be associated with arterial hypertension. The underlying mechanisms are not fully understood and reversibility by parathyroid surgery is controversial. This study aimed to characterize pressor hormones, vascular reactivity to norepinephrine, and cytosolic-free calcium in platelets in 15 hypertensive patients with hypercalcaemic PHPT before and after successful parathyroidectomy and to compare them with 5 pre-hypertensive patients with normocalcaemic PHPT, 8 normotensive patients with hypercalcaemic PHPT and 15 normal controls. Hypertensive patients with hypercalcaemic PHPT had slightly higher levels of pressor hormones (P < 0.05), enhanced cardiovascular reactivity to norepinephrine (P < 0.05) and increased cytosolic calcium in platelets (P < 0.05) than controls. Pre-hypertensive patients with normocalcaemic PHPT had intermediate values of increased cardiovascular reactivity and cytosolic calcium. Normotensive patients with hypercalcaemic PHPT and normotensive controls had comparable pressor hormone concentrations and intracellular calcium levels. Successful parathyroidectomy was associated with normal blood pressure values and normalisation of pressor hormone concentrations, cardiovascular pressor reactivity and cytosolic free calcium. Our results suggest that parathyroid hypertension is mediated/maintained, at least in part, by functional alterations of vascular smooth muscle cells and can be cured by parathyroidectomy in those patients who do not have primary hypertension.
