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
backgroundThe immune system in endurance athletes may be at risk for deleterious effects of gasous pollutants such as ambient ozone. Therefore, this study was performed to assess the effect of regular aerobic exercise with ozone exposure on peripheral leukocytes populations in male Wistar rats.
methodsTwenty eight 8 weeks old rats were selected and randomly divided into four groups of ozone-unexposed and untrained (control or group 1, n = 6), ozone-exposed and untrained (group 2, n = 6), ozone-unexposed and trained (group 3, n = 8), ozone-exposed and trained (group 4, n = 8). All animals in groups 3 and 4 were regularly running (20 m/min, 30 min/day) on a treadmill for 7 weeks (5 day/week). After the last ozone exposure [0.3 ppm, 30 min per sessions], blood samples were obtained from the cardiac puncture and hematological parameters as well as blood lactate were measured using automatic analyzers. Data were expressed as means (± SD) and analyzed by ANOVA and Pearson's correlation tests at p < 0.05.
resultsAll the hematological parameters differences (except RBC and hemoglobin rate) were significantly higher in the trained groups (p < 0.001). However, ozone-induced leukocytosis in the trained (but not in the sedentary) rats was statistically higher than in the counterpart groups.
conclusionsRepeated acute ozone exposure has more additive effect on peripheral leukocyte counts in active animals. But, more researches are needed to identify effects of ozone exposure on other components of the immune system in athletes and non-athletes.
