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
backgroundPost-cardiopulmonary resuscitation brain injury (PBI) is essentially the cerebral ischemia reperfusion (CIR) injury, which is the main cause of death and long-term disability in patients with cardiac arrest. So far, there is no treatment for PBI; thus, it is urgent to develop new drugs or therapies for the prevention and treatment of brain injury after cardiopulmonary resuscitation. Although multiple constituent herbs or active ingredients of Xinbao Pill (XBP) have shown neuroprotective effects, whether XBP could play a therapeutic role on PBI is still unknown. This study aimed to illustrate the neuroprotective effect of XBP on PBI and probe the underlying mechanisms.
methodWe first performed the cell and animal experiments to validate the protective effect of XBP on neurological function. We next identified the potential differential metabolites via metabolomics analysis. We further conducted a comprehensive network pharmacology analysis including overlap gene analysis, protein-protein interaction network, and gene-biological process-module function network to preliminarily investigate the specific mechanism of action (MOA) of XBP against PBI. Finally, PCR, MTT, ELISA assay, as well as Western blotting experiments were made to validate our proposed molecular mechanisms.
resultThe in vitro experiment showed that XBP could increase cell viability and ameliorate cell morphological damage in PC12 cells exposed to oxygen-glucose deprivation and reoxygenation (OGD/RO) conditions. The in vivo experiment demonstrated that XBP improved the Neurologic Deficit Score (NDS), lowered the Neuron-Specific Enolase (NSE) level as well as reversed the typical neuropathological changes in PBI rats, indicating its neuroprotective effect on PBI. Further metabolomics analysis identified 94 differential metabolites after XBP treatment, and multiple metabolites were highly related to CIR. Moreover, network pharmacology results revealed that the therapeutic effect of XBP on PBI may be relevant to mitochondrial quality control (MQC). Mechanistically, XBP could not only promote the expressions of marker proteins including PGC1α, NRF1, TFAM, OPA1, MFN1 as well as MFN2 in mitochondrial biogenesis and mitochondrial fusion but also inhibit those proteins containing DRP1, MFF, FIS1, p62, PINK1, Parkin as well as LC3 in mitochondrial fission and mitophagy. Finally, AMP-activated protein kinase (AMPK) inhibitor was demonstrated to play a crucial role in regulating MQC.
conclusionsOur study first determined that XBP might be an underlying anti-PBI formula, which also deciphered the potential MOAs of XBP against PBI by a network pharmacology approach combined with in vivo and in vitro experimental validation.
