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 progression of periodontal disease (PD) involves the action of oxidative stress mediators. Antioxidant agents may potentially attenuate the development of this condition. Thus, we aimed to evaluate the effects of different doses of humic acid (HA), extracted from biomass vermicomposting, on redox status and parameters related to PD progression in rats. Fifty-four adult male Wistar rats were distributed into six experimental groups (control; PD; PD + 40 mg/kg of HA; PD + 80 mg/kg of HA; PD + 160 mg/kg of HA; PD + 320 mg/kg of HA). HA was administered by gavage for 28 days, and PD was induced by ligature on the mandibular first molars on the 14th day of treatment. After euthanasia, alveolar bone loss, oxidative stress in the gum and erythrocytes, serum levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), and creatinine were analyzed. Animals treated with HA showed less bone loss at the dose of 80 mg/kg compared to the untreated PD group (p < 0.05). Animals treated with HA at doses higher than 80 mg/kg showed improvements in local and systemic redox status parameters (total antioxidant activity, thiobarbituric reactive substances, carbonyl derivatives, and superoxide dismutase) compared to the PD group (p < 0.05). Treatment with HA reduced serum levels of creatinine (at doses of 80 and 160 mg/kg) and AST (at doses of 40 and 80 mg/kg) compared to the PD group (p < 0.05). HA treatment attenuated alveolar bone loss and improved local and systemic oxidative stress parameters in ligature-induced PD rats.
