The Association Between HbA1c Levels And Hematological Biomarkers in Adults with Type 2 Diabetes Mellitus: A Retrospective Study.

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
Background: Type 2 Diabetes Mellitus (T2DM) is associated with chronic hyperglycemia that contributes to oxidative stress and alterations in hemostatic and hematological pathways, potentially leading to measurable changes in routine blood parameters. These biomarkers may provide early indications of metabolic or vascular complications. This study investigates the association between glycated hemoglobin (HbA1c) levels and hematological and hemostatic abnormalities in Saudi adults with T2DM. Methods: This retrospective study analyzed laboratory records of 651 adult patients categorized into four glycemic groups based on HbA1c levels: normal (<5.7%), prediabetes (5.7-6.4%), controlled diabetes (6.5-7.9%), and uncontrolled diabetes (≥8.0%). Hemostatic parameters and red and white blood cell indices were compared across groups. Multiple regression analysis was performed to evaluate associations between demographic and clinical characteristics and hematological outcomes. Results: Statistically significant differences in platelet counts were observed between the prediabetes group and both the controlled and uncontrolled diabetes groups. Red and white blood cell counts were significantly higher in the controlled and uncontrolled groups than in the normal and prediabetes groups. Regression analysis further identified sex, age, and comorbidity as key predictors of several hematological markers. Conclusion: This study demonstrates significant hematological variations across HbA1c-defined glycemic groups, indicating that worsening glycemic control is associated with measurable changes in platelet counts and red and white blood cell parameters. These findings suggest that routine hematological profiles may serve as supportive indicators for identifying patients at increased risk of glycemic deterioration or hematologic complications, offering potential value in early clinical assessment and monitoring of T2DM.
