A scanning electron microscopic study of the opossum nasal cavity prior to and shortly after birth.

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 nasal cavities of opossums prior to and shortly after birth were examined by scanning electron microscopy. Numerous morphologically mature olfactory receptor neurons are observed in the dorso-rostral-most extent of the olfactory epithelium positioned adjacent to the opening of the nares in all prenatal stages and newborn animals examined. The remainder of the olfactory epithelium, occupying a more dorso-caudal position within the nasal cavity, is undifferentiated, and lacks morphologically mature receptor neurons. A short transition zone of stratified squamous epithelium lies between the epithelium lining the nares and olfactory epithelium. It forms an abrupt junction with the latter. The remainder of the nasal cavity in this group of animals is lined by a non-ciliated pseudostratified type (undifferentiated respiratory) of epithelium. By the end of the second postnatal week the morphologically mature olfactory epithelium is no longer observed in the vestibular area of the nasal cavity, which is lined by stratified squamous epithelium at this time. Mature receptor neurons are now observed within the olfactory epithelium lining the roof of the nasal cavity and covering the turbinates. The greater part of the nasal cavity is lined by a ciliated respiratory epithelium. It is proposed that the precocious differentiation of mature olfactory receptor neurons within the rostral-most extent of the olfactory epithelium just prior to birth is important in guiding the newborn young to the pouch.
