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
Tributyltin (TBT) is an antiestrogenic endocrine disrupting compound used in the production of plastic, timber, and aquatic antifouling paints. Previous studies focusing on short-term effects of TBT exposure have identified immediate detrimental effects. Here, we evaluate whether a transient (24 h) exposure to TBT during development can cause persistent effects that remain after removal from treatment. Zebrafish (Danio rerio) larvae were exposed to environmentally relevant concentrations of TBT (0.04 and 0.4 μg/L) when they were either 3- or 7-days post-fertilization (dpf). After exposure, larvae were returned to recovery conditions and assessed 2-weeks, 4-weeks, or > 5 months postexposure. Exposure to 0.4 μg/L TBT at 3 dpf decreased total and distal retinal thicknesses. Adult (>5 month) photopic electroretinograms revealed physiological changes to photoreceptor a-wave and ON-bipolar cell b-wave components, with greater deficits in the 0.4 μg/L group. TBT exposure at 7 dpf significantly increased retinal inner plexiform layer thickness at 2-weeks, an effect that persisted to adulthood. Adult electroretinograms were also altered, with 0.04 μg/L TBT increasing and delaying a-wave and OFF-bipolar d-wave responses and increasing b-wave amplitude. Thus, the impact of TBT exposure depends on both concentration and exposure age, with retinal sequelae characterized by early anatomical and later physiological deficits. These data suggest that TBT exposure during critical periods of visual system development causes persistent age- and concentration-dependent deficits that are specific to the retina, revealing a previously unknown effect of this compound.
