H19 and ischemic stroke: The likelihood ratio scatter plot revealed that the studies by Ahmed Elsabagh DT et al. [58] (lncRNA GAS5), Asmaa Mohammed et al. [53] (lncRNA NBAT1), and Tarek K Motawi et al. [59] (lncRNA H19) were in the upper left quadrant, indicating that these two lncRNAs can be used to both exclude and confirm ischemic stroke (Figure 4B).
