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

key points and practical recommendations•  α Antagonists lower blood pressure by selectively blocking post-synaptic α(1) -adrenoreceptors, which antagonizes catecholamine-induced constriction of the arterial and venous vascular beds. •  α(1) -Adrenoreceptor antagonists are not indicated for initial, first-line antihypertensive therapy; however, they can be added to most other antihypertensive drug classes in--preferably diuretic-containing--drug regimens. •  When used over time, these agents cause expansion of the extracellular fluid and plasma volumes that typically manifests as weight gain and an attenuation of the blood pressure-lowering efficacy in persons who are consuming usual amounts of dietary sodium. •  Utilization of α(1) -adrenoreceptor antagonists with diuretics such as chlorthalidone or hydrochlorothiazide is beneficial because these agents minimize the α antagonist-induced expansion of the extracellular and plasma volumes while providing significant incremental reductions in blood pressure. •  α(1) -Adrenoreceptor antagonists are especially useful in men with benign prostatic hypertrophy because they increase mean and peak urinary flow rates as well as reduce lower urinary tract symptoms. •  α(1) -Adrenoreceptor antagonists are contraindicated in persons with heart failure because of their aforementioned ability to expand extracellular and plasma volumes.
