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 purpose of the present work was to determine the response in growth performance and spermatozoa characteristics of Windsnyer boars supplemented with progressive levels of α-tocopherol. Twenty Windsnyer boars aged 12 weeks with an average body weight of 19.5 ± 2.67 kg were used. Each boar was housed individually in a 1.54 × 0.8 m pen in environmentally controlled house with the temperature ranging from 22 to 25 °C. Five boars were randomly assigned to each diet containing 0, 40, 70 and 90 IU of α-tocopherol. The growth performance experiment lasted for 12 weeks. Subsequently, boars were humanely slaughtered for analyses of testicular development and spermatozoa characteristics. Polynomial regression was used to analyse data. There was a linear response (P < 0.05) in average daily gain and feed conversion ratio as α-tocopherol levels increased. Left and right testicular weights showed a linear increase (P < 0.05) with increasing levels of α-tocopherol. Weights of left and right epididymis exhibited quadratic response (P < 0.05). Seminiferous tube area responded in a quadratic fashion (P < 0.05). There was a quadratic relationship (P < 0.05) between semen volume, straight-line velocity and live spermatozoa. Dead spermatozoa and head abnormalities exhibited linear decrease (P < 0.05). In conclusion, inclusion of α-tocopherol improved growth performance and fertility of Windsnyer boars.
