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

Background: The molecular mechanisms governing adaptive neuroprotection during the postpartum period remain unknown. We hypothesized that circulating exosomes contain bioactive cargo (such as Hsp20) that confer neuroprotection against ischemic injury during the postpartum period. Methods: Exosomes were isolated from plasma of postpartum female mice (ppExos) and control female mice, and from serial blood samples obtained from healthy human volunteers during pregnancy (3rd trimester) and again on postpartum day 2. Exosomal size and protein markers were confirmed Results: ppExos significantly reduced infarct volumes and improved neurological deficits post-MCAO in both young and aged female mice.
