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. Bovine tracheal smooth muscle cells were established in culture to study agonist-induced phosphoinositide (PI) hydrolysis in this tissue. 2. Bradykinin (0.1 nM-10 microM) evoked a concentration-dependent increase (log EC50 (M) = -9.4 +/- 0.2; n = 8) in the accumulation of total [3H]-inositol phosphates in cultured tracheal smooth muscle cells whereas the selective B1 receptor agonist des-Arg9-bradykinin (10 microM) was significantly less effective (16% of bradykinin maximal response; relative potency = 0.2 with respect to bradykinin = 100). 3. The bradykinin-induced increase in PI hydrolysis was unaffected by the B1 receptor antagonist des-Arg9[Leu8]-bradykinin (1 nM-1 microM) but showed marked attenuation in the presence of the B2 receptor antagonists D-Arg,[Hyp3,D-Phe7]-bradykinin (10 nM-10 microM) or D-Arg[Hyp3,Thi5,8,D-Phe7]-bradykinin (10 nM-10 microM). The estimated KB values obtained for these two compounds, assuming competitive antagonism, were 40 +/- 14 nM and 8.6 +/- 2.8 nM for D-Arg,[Hyp3,D-Phe7]-bradykinin and D-Arg[Hyp3,Thi5,8,D-Phe7]-bradykinin respectively. 4. We conclude that bradykinin B2 receptors are expressed in cultured bovine tracheal smooth muscle cells and are coupled to PI hydrolysis mechanisms.
