Analysis of ciliary band formation in the mollusc Ilyanassa obsoleta.
Article in Development genes and evolution, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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
Two primary ciliary bands, the prototroch and metatroch, are required for locomotion and in the feeding larvae of many spiralians. The metatroch has been reported to have different cellular origins in the molluscs Crepidula fornicata and Ilyanassa obsoleta, as well as in the annelid Polygordius lacteus, consistent with multiple independent origins of the spiralian metatroch. Here, we describe in further detail the cell lineage of the ciliary bands in the gastropod mollusc I. obsoleta using intracellular lineage tracing and the expression of an acetylated tubulin antigen that serves as a marker for ciliated cells. We find that the I. obsoleta metatroch is formed primarily by third quartet derivatives as well as a small number of second quartet derivatives. These results differ from the described metatrochal lineage in the mollusc C. fornicata that derives solely from the second quartet or the metatrochal lineage in the annelid P. lacteus that derives solely from the third quartet. The present study adds to a growing body of literature concerning the evolution of the metatroch and the plasticity of cell fates in homologous micromeres in spiralian embryos.
