Evolutionary and developmental origins of the vertebrate dentition.
Review in Journal of anatomy, 2009. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 30 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
According to the classical theory, teeth derive from odontodes that invaded the oral cavity in conjunction with the origin of jaws (the 'outside in' theory). A recent alternative hypothesis suggests that teeth evolved prior to the origin of jaws as endodermal derivatives (the 'inside out' hypothesis). We compare the two theories in the light of current data and propose a third scenario, a revised 'outside in' hypothesis. We suggest that teeth may have arisen before the origin of jaws, as a result of competent, odontode-forming ectoderm invading the oropharyngeal cavity through the mouth as well as through the gill slits, interacting with neural crest-derived mesenchyme. This hypothesis revives the homology between skin denticles (odontodes) and teeth. Our hypothesis is based on (1) the assumption that endoderm alone, together with neural crest, cannot form teeth; (2) the observation that pharyngeal teeth are present only in species known to possess gill slits, and disappear from the pharyngeal region in early tetrapods concomitant with the closure of gill slits, and (3) the observation that the dental lamina (sensu Reif, 1982) is not a prerequisite for teeth to form. We next discuss the progress that has been made to understand the spatially restricted loss of teeth from certain arches, and the many questions that remain regarding the ontogenetic loss of teeth in specific taxa. The recent advances that have been made in our knowledge on the molecular control of tooth formation in non-mammalians (mostly in some teleost model species) will undoubtedly contribute to answering these questions in the coming years.
