Table 2 Presentation of the entire data in total numbers and corresponding percentages

From: Prevalence of low alkaline phosphatase activity in laboratory assessment: Is hypophosphatasia an underdiagnosed disease?

  Total number of ALP activity measurements Number of ALP activity < 30 U/L Percentage of ALP activity < 30 U/L (%) Total number of PLP measurement in the group of ALP activity < 30 U/L Percentage of measured PLP values in the group of ALP activity < 30 U/L (%) Total number of elevated PLP in the group of ALP activity < 30 U/L Percentage of elevated PLP in the group of ALP activity < 30 U/L (%) Estimated prevalence of ALP activity < 30 U/L and elevated PLP*
All 6.918.126 585.287 8.46 3.447 0.59 210 6.09 0.52% (1/194)
Men 3.302.192 275.402 8.34 1.643 0.60 110 6.69 0.56% (1/179)
Women 3.615.934 309.885 8.57 1.804 0.58 100 5.54 0.48% (1/210)
  1. To calculate the estimated prevalence, the following formula was used * (number of ALP activity < 30 U/L) × (percentage of elevated PLP)/total number of ALP activity measurement
