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
Objectives: Using histopathological and immunohistochemical methods, we aimed to examine the dose-dependent effects of chronic caffeine consumption on the recovery of burn wounds in an Materials and Methods: Forty-five rats were randomly assigned to a high-dose group (20 mg/kg per day for eight weeks; n=15), a low-dose group (10 mg/kg per day for eight weeks; n=15), or a control group (n=15). The burn model was created in rats. The groups were separated into three subgroups (n=5) based on the day after injury (7 Results: Successful wound healing was noted in rats treated with low doses of caffeine, similar to the control group. Pathology revealed low re-epithelization, low inflammation, and high granulation in the high-dose group. In addition, there was a significant difference between the control and high-dose groups regarding the immunohistochemical reactivity of αVβ3 integrin, vascular endothelial growth factor (VEGF), and matrix metalloproteinase 9 (MMP-9) ( Conclusion: We demonstrated that chronic caffeine consumption in rats adversely affects the recovery process of wounds in a dose-dependent manner. This effect may occur through delayed wound healing via the molecules MMP-9, αVβ3 integrin, and VEGF. Treatment that modulates these molecules can lead to enhanced and quicker recovery of damaged skin in coffee lovers.
