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
This study investigated maternal and their pup neurobehaviour following nicotine exposure during gestational and postnatal periods and neuroprotective effect of Omega-3 fatty acids. Thus, the study used thirty pregnant female Wistar rats for this study. Groups I and II (nonpregnant and pregnant) were treated with 1 ml/kg/day of normal saline for 42 days; III was treated with 4 mg/kg/day of nicotine for 42 days; IV-VI were co-administered nicotine 4 mg/kg and 100, 300, 600 mg/kg/day of Omega-3 fatty acids respectively for 42 days. Results: The beam walk time of the mother rats in groups III and IV were significantly higher when compared with other groups. Similarly, the beam walks time of the pups of groups III and IV were significantly higher when compared with the pups of the mother rats in other groups. The brain dopamine and serotonin levels of mother rats in groups III, IV and V were significantly higher when compared with other groups. Also, the brain dopamine and serotonin levels of the pups in groups III and IV were significantly higher when compared with the pups in other groups. The reduced glutathione and catalase of mother and pup rats in groups III and IV were significantly lower when compared with other groups. Photomicrographs of cerebellum and hippocampus of the rats treated with nicotine showed scattered arrangement of pyramidal cells with vacuolated neurons. These alterations were significantly reversed with Omega-3 fatty acids following nicotine exposure. Conclusions. Omega-3 fatty acids at 300 and 600 mg/kg ameliorated nicotine-induced neurotoxicity in mother rats and their pups.
