A group of 250 women over the age of 40 are recruited for a study to determine the effects that calcium has on bone health. Half

of the participants are given a calcium supplement and the other half are given a placebo. If 13 women on calcium develop osteomalacia and 27 women not on the placebo develop osteomalacia, the relative risk for developing osteomalacia for women over 40 on a calcium supplement is 0.48 when compared to those women not taking a calcium supplement. This indicates that taking calcium has no effect on the population of interest's health because the relative risk is less than 1.0.

It could be temporary resting period (so when cell again required, or damaged got fixed) then the cells will again join the cycle and continue to divide again or it can also be permanent for example neurons, which are resting in G0 phase and never divides again.</span>
