Carvacrol protects rats against bleomycin-induced lung oxidative stress, inflammation, and fibrosis.

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
The main objective of this study was to investigate the potential efficacy of carvacrol (CAR) in mitigating bleomycin (BLM)-induced pulmonary fibrosis (PF). Sixty-six male Wistar rats were assigned into two main groups of 7 and 21 days. They were divided into the subgroups of control, BLM, CAR 80 (only for the 21-day group), and CAR treatment groups. The CAR treatment groups received CAR (20, 40, and 80 mg/kg, orally) for 7 or 21 days after an instillation of BLM (5 mg/kg, intratracheally). Results indicated that BLM significantly increased total cell count in bronchoalveolar lavage fluid and the percentages of neutrophils and lymphocytes, and reduced the percentage of macrophages. CAR dose-dependently decreased total cell count and the percentage of neutrophils and lymphocytes. CAR significantly reduced thiobarbituric acid reactive substances and hydroxyproline levels and elevated the total thiol level and catalase, superoxide dismutase, and glutathione peroxidase activities in BLM-exposed rats. Furthermore, CAR decreased the transforming growth factor-β1, connective transforming growth factor, and tumor necrosis factor-α on days 7 and 21. BLM increased interferon-γ on day 7 but decreased its level on day 21. However, CAR reversed interferon-γ levels on days 7 and 21. Based on histopathological findings, BLM induced inflammation on days 7 and 21, but for induction of fibrosis, 21-day study showed more fibrotic injuries than the 7-day group. CAR showed the improvement of fibrotic injuries. The effect of CAR against BLM-induced pulmonary fibrosis is possibly due to its antioxidant, anti-inflammatory, and antifibrotic activity.
