Neural tube defect risk per 10 000 births | Red blood cell folate concentration (nmol/L)* | 95% uncertainty interval† |
---|---|---|
40 | 380 | 320 to 449 |
20 | 580 | 510 to 640 |
10 | 870 | 790 to 960 |
6 | 1180 | 1050 to 1340 |
5 | 1310 | 1150 to 1520 |
Estimates were derived using estimated parameters of neural tube defect risk model; details on model, underlying assumptions, and methods used to develop estimates are provided in supplementary material.
*Median (rounded to nearest 10) of posterior distribution for possible values of red blood cell folate concentration associated with specified level of neural tube defect risk.
†Lower value of this interval is 2.5th centile of posterior distribution for possible values of red blood cell folate concentration associated with specified level of neural tube defect risk; upper value is 97.5th centile of distribution.
