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
objectiveTo explore the novel biomarkers and therapeutic target candidates related to the stasis-heat syndrome of acute intracerebral hemorrhage (AICH).
methodsApplying an isobaric tagging for relative and absolute quantitation-(iTRAQ-) based quantitative proteomic approach, plasma samples from AICH patients with stasis-heat, and AICH patients with non-stasis-heat and healthy control subjects were collected and analyzed to distinguish differentially expressed proteins (DEPs) correlated to AICH with stasis-heat in this block design. The standard Western blot was applied to verify DEPs. Additionally, DEPs were analyzed via bioinformatic platforms and further approved via Ingenuity Pathway Analysis (IPA).
resultsA total of 26 DEPs were found among AICH with the stasis-heat, AICH with non-stasis-heat, and healthy control group. The seven DEPs compared with the non-stasis-heat group are closely related to the pathogenesis of stasis heat. These proteins showed three different protein expression patterns. The alpha-1-b glycoprotein (A1BG) and copper-protein (CP) were up-regulated in the stasis-heat group, but down-regulated in the non-stasis-heat group. Compared with the non-stasis-heat group, the expression abundance of actinin, alpha 1 (ACTN1), carbonic anhydrase I (CA1), peroxiredoxin 2 (PRDX2), and vinculin (VCL) is higher in the stasis-heat group, while the CD44 is the opposite. These differences reflect that stasis-heat syndrome has more severe inflammatory immune response, coagulation disorders and damage. Bioinformatics analysis revealed that a wide variety of cellular and metabolic processes and some signaling pathways were involved in the pathophysiology of AICH with stasis-heat. AICH with stasis-heat syndrome showed more severe inflammatory reactions, tissue damage, and coagulation disorders than non-stasis heat syndrome.
conclusionsThere are differences in the protein expression patterns between the stasis-heat syndrome and non-stasis-heat syndrome. These differences reflect that stasis-heat syndrome has more severe damage. CD44, CP, ACTN1, CA1, VCL, PRDX2, and A1BG could be the potential biomarkers and therapeutic target candidates of the stasis-heat subtype. This study provides a reasonable explaination for Liangxue Tongyu decoction through anti-inflammatory and brain protection treatment.
