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
purposeThis study aimed to determine the optimal combination mode of intermittent pneumatic compression (IPC) when combined with hyperthermia (IPCH) at varying temperatures to prevent lower extremity deep vein thrombosis (DVT) following orthopedic surgery.
methodsHemodynamic data from a previous experiment on the physiological state and the IPCH (40°C) group were utilized as the control group. Twenty adult male white rabbits, weighing 2.6±0.3 kg, underwent simulated hip surgery and were randomly assigned to the IPCH (42°C) group or the IPCH (45°C) group, with 10 rabbits in each group. IPCH treatment at 42°C and 45°C was administered to the respective groups on the first day post-operation. Hemodynamic data were assessed before and after treatment, followed by finite element hemodynamic analysis using analytical fluid dynamics.
resultsIn the IPCH (45°C) group, the blood flow velocity distribution vector, total deformation of the femoral vein and venous valve, and equivalent stress of the venous valve were significantly superior compared to the IPCH (40°C) and IPCH (42°C) groups. The increase in equivalent stress of the femoral vein was slightly less than in the IPCH (42°C) group, albeit not statistically significant.
conclusionIPCH at 45°C demonstrates superior efficacy in enhancing deep venous blood return in the lower extremities compared to IPCH at 40°C and 42°C. Moreover, it maintains the femoral vein and venous valve closer to their physiologic state without elevating the risk of injury or rupture.
