1 · What the graph read from it

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.

2 · The registry

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 postcanine teeth of mangabeys (members of Cercocebus and Lophocebus) have figured prominently in discussions about the relationship between hard-object feeding and dental form. Grey-cheeked mangabeys (Lophocebus albigena) and sooty mangabeys (Cercocebus atys) both have thickly enameled posterior teeth. Thick enamel in the former is argued to be response to fallback consumption of hard-object foods, whereas in the latter, this feature is thought to have evolved in response to routine consumption of hard-object foods year-round. Our recent analyses reveal aspects of dental form beyond thick enamel that render C. atys posterior teeth better suited to process hard-object foods and resist fracture than those of L. albigena. We argue that the different feeding regimes of these two mangabey species had different effects on the evolution of their posterior teeth. Here, we detail these differences within the context of the fallback food paradigm. These results may ultimately help us detect modes of hard-object feeding in the fossil record.
