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
Previous studies have demonstrated that several types of human stem cells of non-dental origin can be induced to differentiate into enamel-secreting ameloblasts after recombined with mouse embryonic dental mesenchyme. However, the successful rate of ameloblastic differentiation is about rather low, which presents a major obstacle for future stem cell-based whole tooth bioengineering. Previous studies have shown that cultures at reduced temperature could improve the differentiation capability of stem cells in tissue engineering. In this study, we systematically investigated the effects of low temperature on the viability, proliferation and stemness of human keratinocytes stem cells (hKSCs) in cell culture and further examined ameloblastic differentiation of the hKSCs in human-mouse recombinant chimeric tooth germs. Our results demonstrated that low temperature indeed reduces growth rate and maintains healthy undifferentiated morphology of hKSCs without any effects on cell viability. Moreover, examination of stemness makers revealed improved stemness of hKSCs cultured at low temperature with increased expression of stemness markers K15, CD29 and p63 and decreased expression differentiation marker K10, as compared to those cultured at 37 °C. These low temperature treated hKSCs, when recombined with mouse embryonic dental mesenchyme, exhibited significantly increased rate (40%) of ameloblastic differentiation, as compared to that (17%) in tissue recombinants with those hKSCs treated at standard temperature. Our studies demonstrate that low temperature cell culture improves the stemness and plasticity of hKSCs, which in turn enhances ameloblastic differentiation capability of the stem cells in bioengineered teeth.
