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
Our previous work demonstrated an important role of EpCAM in the regulation of pancreatic cell adhesion, growth and differentiation. Here we investigated the consequences of human EpCAM (hEpCAM) overexpression under the control of the MMTV-LTR promoter, known to drive robust gene expression in a number of ductal epithelia, including the pancreas. In this animal model (MMTV-hEpCAM) we uncovered a striking pancreatic phenotype exhibiting a 12-fold increase in the islet cell mass, with normal expression patterns of insulin and the transcription factor PDX-1. Intriguingly, these large islet clusters revealed an altered architectural organization of α- and δ-cells that appeared interspersed with β-cells in the islet cores. This suggests an effect of the hEpCAM transgene on the function of other cell adhesion molecules that we have previously shown to regulate islet cell type segregation. Consistent with this finding, we show that the pancreatic epithelium in MMTV-hEpCAM transgenic mice exhibits a redistribution of β-catenin, a known regulator of E-cadherin-mediated adhesions. Collectively, these results provide an important in vivo validation of hEpCAM signaling properties in normal epithelia and offer unique opportunities to further explore the function of this glycoprotein in select pancreatic cell lineages to elicit islet cell expansion, and/or regeneration in diabetes.
