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). Here, GAS5 is linked to ischemic stroke.
