Risk of open neural tube defects in relation to certain maternal features of the metabolic syndrome (MetSyn)
| Prevalence of MetSyn | Odds ratio (95% CI) | |||||
| Model | No. features of MetSyn | No. (%) cases | No. (%) controls | Crude | Adjusted** | P-value for trend |

| 1 (n = 135) | 32 (36.0) | 103 (23.7) | 1.9 (1.2–3.1) | 1.9 (1.1–3.4) | ||

*Not all participants had a serum sample available for hsCRP evaluation
**Adjusted for maternal age (1-year increments), serum folate concentration and low income status.
