Comparison of topical hypericum perforatum and metformin effectiveness in wound healing in streptozotocin-induced diabetic rats.

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
Purpose: Our study aimed to assess and compare the effectiveness of topically applied Hypericum perforatum (HP) and metformin on wound healing in diabetic rats. Methods: Thirty-two male Wistar rats (8-10 weeks old, 250 ± 50g) were divided into four groups of eight rats each: Control, Diabetes mellitus (DM), Metformin (Met), and HP. Diabetes was induced in all experimental rats except the control group using streptozotocin (STZ) (60mg/kg, intraperitoneal). A full-thickness skin defect was created in all rats. Two milliliters (ml) of sterile saline were administered to the Control and DM groups, two ml of metformin (10% gel, topical) to the Met group, and two ml of HP (olive oil extract) to the HP group, repeated every 24 hours for 14 days. The condition of the lesions was monitored on days 0, 3, 7, 10, and 14, and the extent of contraction and granulation tissue formation was documented. At the 14 Results: The baseline characteristics of the rats before the study showed no significant differences between the groups (p>0.05). The HP group had the smallest final wound size and the highest wound contraction percentages from day 0 to 14 (p<0.001 for both). There was no statistically significant difference among the groups in the collagen index (p=0.118). The fibroblast density scores in the DM group were significantly lower than those in the other groups (p=0.004). The hypertrophic index values of the HP group were the highest compared to the other groups (p=0.003). Although the HP and control groups exhibited higher TGF-β percentages and H scores than the other groups, these differences were not statistically significant (p=0.660 and p=0.647). Conclusion: Topically applied HP in uncontrolled DM rats improved wound healing scores more than the non-diabetic controls. Metformin also significantly enhanced healing in DM rats, with results comparable to controls. Since HP and metformin are easily accessible, further research could lead to cost-effective treatments for wound healing issues in DM patients.
