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

Changed NMDA receptor (NMDAr) physiology is implicated with cognitive deficit resulting from conditions ranging from normal aging to neurological disease. Using intermittent hypoxia (IH) to experimentally model untreated sleep apnea, a clinical condition whose comorbidities include neurocognitive impairment, we recently demonstrated that IH causes a pro-oxidant condition that contributes to deficits in spatial memory and in NMDAr-dependent long-term potentiation (LTP). However, the impact of IH on additional forms of synaptic plasticity remains ill-defined. Here we show that IH prevents the induction of NMDAr-dependent LTP and long-term depression (LTD) in hippocampal brain slices from mice exposed to ten days of IH (IH
