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

STUDY

objectivesAdenosine modulates sleep via A(1) and A(2A) receptors. As the A(1) receptor influences Ca(V)2.1 channel functioning via G-protein inhibition, there is a possible role of the Ca(V)2.1 channel in sleep regulation. To this end we investigated transgenic Cacna1a R192Q mutant mice that express mutant Ca(V)2.1 channels that are less susceptible to inhibition by G-proteins. We hypothesized that Cacna1a R192Q mice could show reduced susceptibility to adenosine, which may result in a sleep phenotype characterized by decreased sleep.

designR192Q mutant and littermate wild-type mice were subjected to a 6-h sleep deprivation, treatment with caffeine (a non-specific adenosine receptor antagonist which induces waking), or cyclopentyladenosine (CPA, an A(1) receptor specific agonist which induces sleep). MEASUREMENTS AND

resultsUnder baseline conditions, Cacna1a R192Q mice showed more waking with longer waking episodes in the dark period and less non-rapid eye movement (NREM) sleep, but equal amounts of REM sleep compared to wild-type. After treatment with caffeine R192Q mice initiated sleep 30 min earlier than wild-type, whereas after CPA treatment, R192Q mice woke up 260 min earlier than wild-type. Both results indicate that Cacna1a R192Q mice are less susceptible to adenosinergic input, which may explain the larger amount of waking under undisturbed baseline conditions.

conclusionWe here show that adenosinergic sleep induction, and responses to caffeine and CPA, are modified in the R192Q mutant in a manner consistent with decreased susceptibility to inhibition by adenosine. The data suggest that the A(1) receptor modulates sleep via the Ca(V)2.1 channel.
