The mediating role of inflammation in the association between coagulation parameters and diabetic kidney diseases in patients with type 2 diabetes mellitus: a muti-center cross-sectional retrospective study in Southwest China from 2013 to 2022.

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 aims to investigate the association between coagulation parameters and diabetic kidney diseases (DKD) with a specific focus on evaluating the potential mediating effects of inflammation.
methodsA total of 10,523 patients from 6 different centers were enrolled in our study. The association between coagulation parameters and DKD was evaluated using the logistic regression model and subgroup analysis. The predictive ability of coagulation parameters for DKD was assessed through a series of investigations including receiver operating characteristic curve (ROC) analysis and decision curve analysis (DCA). Additionally, mediation analysis was performed to examine the potential role of different inflammatory factors on the association between coagulation parameters and DKD.
resultsMultivariate logistic analysis revealed that fibrinogen (FIB) (OR = 1.086, 95%CI = 1.035–1.039, p-value < 0.001) and prothrombin activity (PTA) (OR = 1.015, 95%CI = 1.011–1.019, p-value < 0.001) were positively associated with DKD. Conversely, prothrombin time (PT) was negatively associated with DKD when converted into a categorical variable (Tertile 3: OR = 0.701, 95%CI = 0.594–0.827, p-value < 0.001). Moreover, PT, PTA, and FIB were examined for their predictive ability and PT performed best in the prediction of DKD (AUC: 0.583, 95%CI: 0.569–0.598). Mediation analysis demonstrated that neutrophils attenuated 8.27% of the total effects in the DKD-PTA relationship and mediated 3.74% of the relationship between DKD and PT. Moreover, multiple inflammation parameters including eosinophils and albumin were also found to mediate the association between DKD and coagulation parameters.
conclusionThese findings suggest that coagulation parameters are cost-effective screening tools for early DKD detection. Inflammation parameters are identified to mediate the association between coagulation parameters and DKD while the internal mechanism requires further exploration.
