Table 2: The table shows the (mean±SE) of the vitamin D, PTH and BMI for the total Employees and their subgroups [(Physicians, Nurses and Administration and for the football players and their subgroups resident at (Nazareth, Sakhnin and Arrabeh)]. The table also shows a statistically significant difference in the level of vitamin D in favor of the subgroups of Administration employees (20.9±0.6) versus the levels of vitamin D among Nurses (17.93±0.7). The statistical significant difference is marked by red star (*), p<0.05)].
