Forest Plot for parathormone (A) and Vitamin D (B). (Legends/footnotes) Group differences in paratharmone (A) and vitamin D (B) between the occupationally Pb exposed and unexposed control workers. Forest plot for association between occupational Pb exposure and Paratharmone (A) and Vitamin D (B) levels. (Legends/footnotes): Forest plot revealing the group mean differences in parathormone in pg/dl (A) and vitamin D in ng/dl (B) between the occupationally Pb exposed workers and control participants. The square and whisker (horizontal line) represent respectively the mean difference and 95% confidence interval of individual studies. The length and width of the diamond indicate respectively the pooled mean difference and 95% confidence interval derived from random-effect analysis.
