Association Between Uncontrolled Type 2 Diabetes mellitus and Concentrated Growth Factor Composition: A Cross-Sectional Study.
Article in Journal of International Society of Preventive & Community Dentistry. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Objective: Concentrated Growth Factor (CGF) is a third-generation autologous platelet concentrate utilized for its high density of bioactive molecules. However, the influence of chronic hyperglycemia on the specific growth factor composition of CGF remains underexplored. This study aimed to quantify and compare the concentrations of IGF-1, VEGF-A, and TGF-β1 in CGF derived from individuals with uncontrolled type 2 diabetes mellitus (T2DM) versus non-diabetic controls. Methods: A cross-sectional study was conducted involving 80 participants: 40 with uncontrolled T2DM (HbA1c > 7%) and 40 non-diabetic controls (HbA1c < 6%). CGF was isolated via a standardized variable-speed centrifugation protocol (Medifuge MF200). Growth factor levels were quantified using validated, high-sensitivity enzyme-linked immunosorbent assays (CV < 10%). Data were analyzed using independent t-tests and Pearson's correlation ( Results: CGF from uncontrolled diabetics exhibited significantly lower mean concentrations of all measured factors compared to controls: IGF-1 (0.42 ± 0.15 vs. 1.58 ± 0.06 ng/mL; Conclusion: Uncontrolled hyperglycemia is associated with a significant quantitative depletion of key regenerative growth factors within CGF, particularly IGF-1 and VEGF-A. These findings suggest that the intrinsic regenerative potential of autologous CGF may be compromised in diabetic patients, indicating a need for optimized glycemic control or adjunctive strategies in clinical regenerative procedures.
