Instability of the barrier effect and natural selection for introgressed alleles could be due to environment-dependent selection, emphasizing the need to consider temporal variation in the strength of natural selection and the stability of the barrier effect at putative barrier loci in future speciation work. The effect of calcium channel blockers (CC on mortality and ischaemic stroke risk in dementia patients is understudied. To calculate the risk of death and ischaemic stroke in dementia patients treated with CCBs, consider
