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 5-hydroxytryptamine (5-HT) receptors mediating vasoconstriction in isolated human small muscular pulmonary arteries (SMPAs) were determined using techniques of wire myography and reverse transcription-polymerase chain reaction (RT - PCR). 2. The agonists 5-HT, 5-carboxamidotryptamine (5-CT, unselective for 5-HT1 receptors) and sumatriptan (selective for 5-HT1B/D receptors) all caused contraction and were equipotent (pEC50s: 7.0+/-0.2, 7.1+/-0.3 and 6.7+/-0.1, respectively) suggesting the presence of a 5-HT1 receptor. 3. Ketanserin (5-HT2A-selective antagonist, 0.1 microM) inhibited 5-HT-induced contractions only at non-physiological/pathological concentrations of 5-HT (>0.1 microM) whilst GR55562 (5-HT1B/1D-selective antagonist, 1 microM) inhibited 5-HT-induced contractions at all concentrations of 5-HT (estimated pKB=7.7+/-0.2). SB-224289 (5-HT1B-selective antagonist, 0.2 microM) inhibited sumatriptan-induced contractions (estimated pKB=8.4+/-0.1) whilst these were unaffected by the 5-HT1D-selective antagonist BRL15572 (0.5 microM) suggesting that the 5-HT1B receptor mediates vasoconstriction in this vessel. 4. RT - PCR confirmed the presence of substantial amounts of mRNA for the 5-HT2A and 5-HT1B receptor subtypes in these arteries whilst only trace amounts of 5-HT1D receptor message were evident. 5. These findings suggest that a heterogeneous population of 5-HT2A and 5-HT1B receptors co-exist in human small muscular pulmonary arteries but that the 5-HT1B receptor mediates 5-HT-induced vasoconstriction at physiological and pathophysiological concentrations of 5-HT. These results have important implications for the treatment of pulmonary hypertension in which the 5-HT1B receptor may provide a novel and potentially important therapeutic target.
