Effects of exercise and walnut oil on CES1 and inflammatory factors in the liver of type 2 diabetic rats.
Article in European journal of medical research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Carboxylesterase 1 (CES1) and inflammatory factors play important roles in regulating lipid metabolism and maintaining glucose homeostasis. Exercise and walnut oil have anti-inflammatory effects, but the effects of exercise and walnut oil on CES1 and inflammatory factors in type 2 diabetes mellitus (T2DM) remain to be revealed. 8-week-old SD male rats were randomly divided into normal control group (NC group, N = 12) and high fat group (HFD group, N = 28) after 1 week of adaptive feeding. HFD rat models were established by high-fat diet and one-time injection of streptozocin. The successfully constructed rats were randomly divided into diabetes control group (T2DM-NC group, N = 6), the diabetes plus moderate intensity exercise group (T2DM-MED group, N = 6), the diabetes plus high intensity intermittent exercise group (T2DM-HIIT group, N = 6), and the diabetes plus walnut oil group (T2DM-WO group, N = 6). After 6 weeks of intervention, ELISAs were used to determine the blood glucose and lipid-related indices of the rats. Histomorphologic changes in the liver were observed by hematoxylin‒eosin staining. The mRNA expression levels of CES1 and inflammatory cytokines were determined by real-time quantitative PCR. The protein expression levels of CES1 and inflammatory factors were determined by immunofluorescence staining. Compared with those in the NC group, in the T2DM-NC group, FBG, TG, LDL-C and HOMA-IR were increased (P < 0.01), FINS activity was decreased (P < 0.01), liver morphology was more disorganized, and CES1 and inflammatory cytokines were highly expressed in the liver tissue (P < 0.05 or P < 0.01). After 6 weeks of intervention, TG levels were significantly decreased (P < 0.05 or P < 0.01), whereas FINS levels were increased (P < 0.05 or P < 0.01), liver morphology was significantly ameliorated, and the CES1, TXNIP and IL-1β expression levels were decreased (P < 0.05 or P < 0.01) in the T2DM-MED, T2DM-HIIT and T2DM-WO groups when compared with those in the T2DM-NC group. The T2DM rats presented abnormal blood glucose and lipid levels, and CES1, TXNIP and IL-1β were highly expressed in the liver. Exercise and walnut oil intervention ameliorated the glycolipid metabolism and liver morphology, and reduce the expression of CES1, TXNIP and IL-1β in the liver.
