Remote ischaemic preconditioning on gene expression and circulating proteins after subacute laparoscopic cholecystectomy: randomized clinical trial.
Trial report in BJS open, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundSurgical stress may lead to postsurgical hypercoagulability, endothelial dysfunction and systemic inflammation, which can impact on patient recovery. Remote ischaemic preconditioning is a procedure that activates the body's endogenous defences against ischaemia and reperfusion injury. Studies have suggested that remote ischaemic preconditioning has antithrombotic, antioxidative and anti-inflammatory effects. The hypothesis was that remote ischaemic preconditioning reduces surgery-induced systemic stress response.
methodDuring a 24-month period (2019-2021), adult patients undergoing subacute laparoscopic cholecystectomy due to acute cholecystitis were randomized to remote ischaemic preconditioning or control. Remote ischaemic preconditioning was performed less than 4 h before surgery on the upper arm. It consisted of four cycles of 5 min ischaemia and 5 min reperfusion. The gene expression of 750 genes involved in inflammatory processes, oxidative stress and endothelial function was investigated preoperatively and 2-4 h after surgery in both groups. In addition, changes in 20 inflammation- and vascular trauma-associated proteins were assessed preoperatively, 2-4 h after surgery and 24 h after surgery.
resultsA total of 60 patients were randomized. There were no statistically significant differences in gene expression 2-4 h after surgery between the groups (P > 0.05). Remote ischaemic preconditioning did not affect concentrations of circulating proteins up to 24 h after surgery (P > 0.05).
conclusionThe study did not demonstrate any effect of remote ischaemic preconditioning on expression levels of the chosen genes or in circulating immunological cytokines and vascular trauma-associated proteins up to 24 h after subacute laparoscopic cholecystectomy in patients with acute cholecystitis.
