Plasma Biomarker Profiling of 2-Hydroxypropyl-β-Cyclodextrin (HPβCD) Treatment in an Aged Mouse Model of Ischemic Stroke.

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
Lipid debris generated after ischemic stroke overwhelms myeloid cells, leading to foam cell-like dysfunction and chronic neuroinflammation. 2-hydroxypropyl-β-cyclodextrin (HPβCD), a cholesterol-mobilizing agent, has been shown to improve recovery and reduce chronic inflammation after stroke by enhancing lipid processing and cholesterol efflux in infarcts. To identify plasma biomarkers of HPβCD activity and gain mechanistic insight into lipid pathway modulation, aged (21-month-old) male mice underwent the distal middle cerebral artery occlusion + hypoxia (DH) model of stroke and received 2 g/kg HPβCD twice daily beginning 1 d after stroke. Plasma metabolomic and lipidomic profiling was performed 4 d after stroke using untargeted (Global Discovery) and targeted (Complex Lipid, Oxysterols, and Lipid Mediators of Inflammation) panels. Acute neuroprotection was assessed by magnetic resonance imaging (MRI) quantification of infarct, ventricle, and hippocampus volumes 2 d after stroke and by plasma neurofilament light (NfL) levels 4 d after stroke. HPβCD treatment did not provide acute neuroprotection; however, HPβCD did induce distinct plasma metabolomic and lipidomic signatures, including decreases in sphingolipids, cholesterol, long-chain fatty acids, 4β-hydroxycholesterol, 7-dehydrocholesterol, and 8-dehydrocholesterol and increases in 27-hydroxycholesterol and 7α-hydroxy-3-oxo-4-cholestenoic acid (7-HOCA), consistent with enhanced cholesterol efflux and metabolism. Pro-inflammatory oxylipins were also suppressed by HPβCD treatment. These results support the role of HPβCD in promoting lipid debris clearance and suppressing inflammatory lipid pathways after stroke and, together with prior studies demonstrating improved long-term recovery, highlight HPβCD as a biomarker-supported therapeutic candidate for stroke recovery.
