Value of Active Warming Devices for Intraoperative Hypothermia Prevention-A Meta-Analysis and Cost-Benefit Analysis.
Synthesis in International journal of environmental research and public health, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
purposeHistorically, studies suggested that intraoperative hypothermia (IH) could result in significant resource consumption, but more recent studies have found the opposite. The purpose of this study is to estimate the value of active warming devices for IH prevention based on synthesized evidence.
methodsA cost-benefit analysis was conducted using the effect of active warming versus passive warming devices for intraoperative hypothermia from a meta-analysis. The item-based aggregated treatment cost approach was adopted to estimate the cost of each adverse event, which was then weighted to calculate the total cost of IH.
resultsIH was associated with higher risks of bleeding, surgical site infection, and shivering compared with normothermia. The cost of one case of IH was $363.80, and the use of active warming devices might save $152.80. Extra investment in active warming (e.g., $291.00) might only be cost-beneficial when the minimum willingness-to-pay is $150.00.
conclusionsSynthesized evidence showed that the cost of IH might be overestimated. Furthermore, the value of using active warming devices remains uncertain because the willingness to pay may vary between decision-makers. As not enough awareness of hypothermia prevention in some countries, further research into the clinical use of active warming devices during major surgeries is warranted.
