Hyperbaric Oxygen Therapy Improved Neovascularisation Following Limb Ischaemia-The Role of ROS Mitigation.
Article in Journal of cellular and molecular medicine, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
Hyperbaric oxygen (HBO) therapy has emerged as a potential treatment, shown to enhance blood flow and angiogenesis. However, specific effects and mechanisms of HBO on limb ischaemia responding to a hypoxic environment remain largely unknown. We aimed to investigate the therapeutic potential of HBO in the treatment of limb ischaemia. Following limb ischaemia surgery, we evaluated the angiogenic capacity in wild-type C57BL/6J mice subjected to HBO treatment (100% oxygen at 3 ATA for 1 h/day for five consecutive days) compared to untreated controls. Notably, through laser Doppler perfusion imaging and CD31 staining mice receiving HBO postlimb ischaemia surgery exhibited significantly enhanced angiogenic capability and reduced ROS expression compared to nontreated counterparts. Additionally, in vitro experiments were conducted to investigate whether HBO could mitigate endothelial cell dysfunction and reactive oxygen species (ROS) production triggered by oxygen-glucose deprivation (OGD). HBO treatment rescued the impaired proliferation, migration and tube formation of endothelial cells following OGD. Mechanistically, HBO upregulated the expression of proangiogenic proteins, including vascular endothelial growth factor (VEGF), haem oxygenase-1 (HO-1), hypoxia-inducible factor 1 (HIF-1) and nuclear factor erythroid 2-related factor 2 (Nrf2). Collectively, HBO treatment shows promise in augmenting the endogenous angiogenic potential and suppressing ROS levels in limb ischaemia.
