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 Muscarinic receptors (M-receptors) in the mammalian heart are predominantly of the M(2)-subtype. The aim of this study was to find out whether there might exist an additional myocardial non-M(2)-receptor. 2 For this purpose, we assessed, in adult rat isolated ventricular cardiomyocytes, carbachol-induced [(3)H]-inositol phosphate (IP) formation, and its inhibition by M-receptor antagonists. 3 Carbachol (10(-7)-10(-3) mol l(-1)) increased IP-formation (maximal increase: 14+/-3% above basal, n=6). This increase was significantly enhanced by pretreatment with pertussis toxin (PTX, 250 ng ml(-1) for 20 h): maximal increase was 31+/-5%, pEC(50)-value was 5.08+/-0.33 (n=6). 4 In PTX-pretreated cardiomyocytes 100 micromol l(-1) carbachol-induced IP-formation was inhibited by atropine (pK(i)-value: 8.89+/-0.10) and by the M(3)-receptor antagonist darifenacin (pK(i)-value: 8.67+/-0.23) but was not significantly affected by the M(1)-receptor antagonist pirenzepine (1 micromol l(-1)) or the M(2)-receptor antagonists AF-DX 116 and himbacine (1 micromol l(-1)). 5 In conclusion, in adult rat cardiomyocytes there exists an additional, non-M(2)-receptor, that is coupled to activation of the phospholipase C/IP(3)-pathway; this receptor is very likely of the M(3)-subtype.
