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
Recently, we have reported that heat shock protein B1 (HSPB1) and purinergic receptor P2X7 (P2RX7) are involved in astroglial autophagy (clasmatodendrosis), following status epilepticus (SE). However, the underlying mechanisms of astroglial autophagy have not been completely established. In the present study, we found that the lacking of P2rx7 led to prolonged astroglial HSPB1 induction due to impaired mitogen-activated protein kinase 1/2 (MAPK1/2)-mediated specificity protein 1 (SP1) phosphorylation, following kainic acid-induced SE. Subsequently, the upregulated HSPB1 itself evoked ER stress and exerted protein kinase AMP-activated catalytic subunit alpha 1 (PRKAA1, AMPK1)/unc-51 such as autophagy activating kinase 1 (ULK1)- and AKT serine/threonine kinase 1 (AKT1)/glycogen synthase kinase 3 beta (GSK3B)/SH3-domain GRB2-like B1 (SH3GLB1)-mediated autophagic pathways, independent of mechanistic target of rapamycin (MTOR) activity in astrocytes. These findings provide a novel purinergic suppression mechanism to link chaperone expression to autophagy in astrocytes. Therefore, we suggest that P2RX7 may play an important role in the regulation of autophagy by the fine-tuning of HSPB1 expression.
