Effect of emotional and neutral declarative memory consolidation on sleep architecture.
Article in Experimental brain research, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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.
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
The relationship between emotional or neutral declarative memory consolidation and sleep architecture was investigated. Thirty university students (21 females) viewed negative, neutral, or positive pictures and rated their valence and arousal in the evening. Participants performed a recognition test 1 h later and then underwent overnight polysomnography. Their post-encoding sleep architecture was compared to a baseline night. Participants returned 6 days following encoding for a second recognition test. Results showed no group (Negative, Neutral, Positive) differences in recognition 1 h or 6 days following encoding. Stage 2 sleep spindle density decreased across all groups following encoding, and recognition after 6 days was positively correlated with Stage 2 sleep spindle density on both nights. There was no change in REM density in any of the groups. This is the first investigation into phasic sleep microarchitecture changes following emotional and neutral declarative learning. Future investigations may benefit from more salient emotional stimuli.
