Sexual dimorphic vulnerability of respiratory control in a neonatal rodent model of fetal alcohol spectrum disorder.

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
Fetal alcohol spectrum disorder (FASD) has been linked to numerous poor neurological outcomes as well as impairments in respiratory neural control. Females are known to metabolize ethanol (EtOH) differently than males suggesting a sexual dimorphic sensitivity to EtOH exposure. We used a rodent model of FASD to investigate whether EtOH disrupts respiratory neural control. Rat pups received a single intraperitoneal injection of 2 different doses (0.8 mg/g or 4.4 mg/g) of EtOH. Whole-body plethysmography was used ∼24 h later to assess ventilatory responses to acute hypoxia (HVR) and hypercapnia (HCVR). Females treated with 4.4 mg/g of EtOH exhibited an attenuated HVR and HCVR, but there was no effect on males, and no effect of 0.8 mg/g on either sex. There was unexpected mortality of unknown causes, especially in females, that occurred 2-3 days after EtOH administration. These data suggest that important ventilatory defense responses in females are impaired following developmental EtOH exposure, and this may be associated with increased risk of later death.
