This function adjusts systolic blood pressure based on the respondent's systolic average blood pressure across six measurements. The adjustment is made using specific correction factors. The adjusted systolic blood pressure is returned as a numeric value.
Details
The function calculates the adjusted systolic blood pressure (SBP_adj) based on the value of BPMDPBPS. If BPMDPBPS is greater than or equal to 0 and less than 996, the adjustment is made using the formula: SBP_adj = 11.4 + (0.93 * BPMDPBPS). Otherwise, if BPMDPBPS is a non-response value (BPMDPBPS >= 996), the adjusted systolic blood pressure is set to NA(b), indicating that the measurement is not available. The adjusted systolic blood pressure is returned as the final output.
