CSV Bulk calculations specifications: FA

This type of CSV allows to get, for each row, adjusted scores according to forearm BMD.

The relationship between bone mineral density (BMD) at the forearm and fracture risk was determined in a meta-analysis of primary data from 11 cohort studies of 35121 men and women. Low forearm BMD was a significant predictor of fracture risk, independently from FRAX®.

This adjustment is only available if femoral neck BMD has NOT been provided.

Input Variables

A CSV input file should always have 14 columns. An optional header can be sent as first line of the CSV file:

Score unit,Country,Age,Sex,BMI,Previous fracture,Parental history,Current smoker,Gluccocorticoid,Rheumatoid Arthritis,Secondary osteoporosis,Alcohol,Femoral neck BMD,Forearm BMD

The first columns are the FRAX variables:

# Col Variable Description Possible Values
1 A Score unit Unit for variable 13 t: T-score, z: Z-score. Unit for parameter 13 (BMD) described below.
2 B Country Code for country and ethnicity Integer. Get valid countries' id from the API.
3 C Age Age in years Positive real number (40-90), can have decimals. Out of bound values will be capped.
4 D Sex Gender 0: men, 1: women
5 E BMI Body Mass Index Positive real number (kg/m²), can have decimals
6 F Previous fracture History of previous fracture 0: no, 1: yes
7 G Parental history Parent(s) with hip fracture history 0: no, 1: yes
8 H Current smoker Current smoking status 0: no, 1: yes
9 I Gluccocorticoid Gluccocorticoid use 0: no, 1: yes
10 J Rheumatoid Arthritis Presence of rheumatoid arthritis 0: no, 1: yes
11 K Secondary osteoporosis Presence of secondary osteoporosis 0: no, 1: yes
12 L Alcohol More than two drinks a day 0: no, 1: yes
13 M Femoral neck BMD Bone mineral density measurement This column should always be empty as this adjustment is only available if femoral neck BMD has NOT been provided.

Then we need the adjustment variable:

# Col Variable Description Possible Values
14 N Forearm BMD Z-score for forearm BMD Real number between -4 and 4. If a number out of range is entered, -4 or 4 will be used.

Output Results

Once processed, you will receive an output file with, for each row, the results append to the original line (the variables above).

# Col Result Description
15 O FRAX MOF wo BMD major osteoporotic fracture risk without BMD
16 P FRAX Hip wo BMD hip fracture risk without BMD
17 Q FRAX MOF w BMD major osteoporotic fracture risk with BMD. This column will always be empty as this adjustment is only available if femoral neck BMD has NOT been provided.
18 R FRAX HIP w BMD hip fracture risk with BMD. This column will always be empty as this adjustment is only available if femoral neck BMD has NOT been provided.
19 S FA MOF wo BMD Adjusted MOF without BMD according to forearm BMD
20 T FA Hip wo BMD Adjusted HIP without BMD according to forearm BMD

Output warning or error reporting

If an error for any adjustments of the row has been triggered, a specific message will be added at the end of the line.
