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
purposeLaryngeal pathologies due to cigarette smoking vary among individuals, whereas some smokers remain disease free. These differences can be explained by multiple factors among individuals. In this context, an animal study was designed to determine if there is any protective effect of aerobic exercise against the detrimental effects of cigarette smoke on laryngeal tissues.
methodsA total of 24 male Wistar albino rats were divided into three groups of eight animals each: control (no smoke exposure), smoking (smoke exposure), and exercise (smoke exposure and exercise) groups. Histopathological (light and electron microscopy) and immunohistochemical (GSTA1, CYP1A1, CYP2E1) evaluations of the vocal folds were performed at the end of experimental period.
resultsExercise group revealed statistically significant decrease in edema (p = 0.03) and inflammatory cell infiltration (p = 0.02) compared to smoking group. In electron microscopic evaluation; cytoplasmic vacuoles were also present in exercise group, but were smaller than smoking group. Edema and swollen mitochondria were also less prominent in exercise group. Condensed chromatin material in the periphery of nucleus was observed only in few cells in exercise group, and observed in more cells in smoking group. GSTA1 expression was higher (p = 0.047) and CYP1A1 expression was lower (p = 0.01) in exercise group than smoking group.
conclusionsOur results indicate that aerobic exercise has a protective role on the larynx against the damaging effect of cigarette smoke. Smokers who exercise regularly may be at a lower risk of cigarette smoke-related laryngeal diseases, as compared with those who do not exercise.
