Fig 1.
Box plots of platelet count for females (dark) and males (light) stratified by age.
Median platelet count is significantly higher in females (p<0.001 in all age strata). Platelet count correlated significantly with age.
Fig 2.
Box plots of platelet count for females (dark) and males (light) stratified by MPV.
Median MPV inversely correlates with platelet counts in females and males (Spearman’s rho = -0.3735; p<0.0001).
Fig 3.
Box plots of MPV for females (dark) and males (light) stratified by age.
Median MPV is similar between males and females and does not correlate with age.

Formulas for 2.5th, 50th and 97.5th percentile of platelet count unadjusted and adjusted for age based on data from 1,491 males and 1,542 females.

Reference intervals age-adjusted and unadjusted for age for platelet count in dependence of mean platelet volume for (A) females and (B) males. Adjustment for age has a minor impact on reference values for platelet count in females and males, when MPV is considered for adjustment.
