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
Conventional methods for obtaining pancreatic β cells are based on simulating the embryonic development phase of endocrine cells via hierarchical differentiation of pluripotent stem cells (PSCs). Accordingly, we attempted to modify the protocols for obtaining insulin-secreting cells (ISCs) by sequential differentiation of a human embryonic stem cell (hESC), using the HS181 cell line. Furthermore, we hypothesize that actual pancreatic endocrine cells may arise from trans-differentiation of mature ductal cells after the embryonic developmental stage and throughout the rest of life. According to the hypothesis, ductal cells are trans-differentiated into endocrine and exocrine cells, undergoing a partial epithelial to mesenchymal transition (EMT). To address this issue, we developed two new protocols based on hESC differentiation to obtain ductal cells and then induce EMT in cells to obtain hormone-secreting islet-like cells (HSCs). The ductal (pre-EMT exocrine) cells were then induced to undergo partial EMT by treating with Wnt3a and activin A, in hypoxia. The cell derived from the latter method significantly expressed the main endocrine cell-specific markers and also β cells, in particular. These experiments not only support our hypothetical model but also offer a promising approach to develop new methods to compensate β cell depletion in patients with type 1 diabetes mellitus (T1DM). Although this protocol of generating islet-like cells from ductal cells has a potential to treat T1DM, this strategy may be exploited to optimize the function of these cells in an animal model and future clinical applications.
