Contribution of the maxillary sinus to the modularity and variability of nasal cavity shape in Japanese macaques.
Article in Primates; journal of primatology, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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 cavity is essential for conditioning of inspired air, and its form likely impacts its function. Since humans and other anthropoids have reduced nasal turbinates when compared to other mammals, variation in relative surface area is mainly brought about by changes to overall nasal architecture. Previous studies of modern humans suggest that variation in the transverse dimensions of the nasal cavity is likely possible because of the presence of the maxillary sinuses. To understand the evolutionary origin of this adaptation, we investigated the nasofacial skeleton of Japanese macaques (Macaca fuscata). We applied computed tomography and geometric morphometrics to test how the nasal cavity shape is correlated with relative maxillary sinus volume and to evaluate how the nasal cavity shape is integrated with the external craniofacial shape. Our results show that the decreasing sinus volume is well associated with the relative expansion of nasal cavity at the middle region compared to the anterior and posterior openings. The nasal cavity shape is not integrated with the external craniofacial shape especially at the middle region as well as the posterior opening. Thus, the maxillary sinus in macaques may contribute to the modularity and variability of the nasal cavity shape, possibly facilitating the adaptive changes in the nasal airways of this species.
