Low-dose iron supplements haemoglobin data [internal outcome-validation study]
Description
Capillary haemoglobin and venous haemoglobin levels of 400 subjects of a trial investigating the efficacy of low-dose iron supplements during pregnancy. Venous haemoglobin levels were observed of approximately 25% of the subjects included in the trial.
Usage
haemoglobin
Format
A data frame with 400 rows and 3 variables:
- capillary
Haemoglobin levels measured in capillary blood (g/L)
- supplement
Low-dose iron supplement (20 mg/d) (0 = no, 1 = yes)
- venous
Haemoglobin levels measured in venous blood (g/L)
Details
This is a simulated data set inspired by a trial investigating low-dose iron supplements <doi:10.1093/ajcn/78.1.145>. A motivating example using the example data can be found here: <doi:10.1002/sim.8359>
