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

Sleep has important functions for every organ in the body and sleep deprivation (SD) leads to disorders that cause irreparable damage. The aim of this study was to investigate behavioral and brain structural alterations in mice deprived of paradoxical sleep for 48 and 72 h. Working memory, aversive memory as well as levels of nitric oxide (NO) and thiobarbituric acid reactive substances (TBARS) in the hippocampus, body striatum, and prefrontal cortex were evaluated. Working memory was affected in the 48- and 72-h SD groups while aversive memory was altered only in the 48-h SD group (p ≤ 0.05). Our findings showed that SD reduces NO levels in most brain areas (p < 0.05): NO levels were unaltered in the striatum of animals sleep-deprived for 48 h. Higher levels of TBARS were observed in all areas of the SD groups (p ≤ 0.05). Thus, we confirmed that SD has duration-dependent effects on behavior as well as on NO and TBARS levels in the brain. Preserved striatum NO levels suggest that this structure is less vulnerable to oxidative stress and is only affected by SD of longer duration. Increased TBARS and reduced NO levels in the hippocampus and prefrontal cortex confirm a central role for both these structures in working memory and aversive memory. Contextual fear conditioning was not affected by longer periods of SD. Thus, our findings suggest that shorter SD time may be more beneficial to avoid aversive memory where this may have implications for the management of posttraumatic stress.
