Table 5 Unadjusted and adjusted matched odds ratios (MOR) for assessing associations between ASD status and quartiles of blood manganese concentrations (BMC) based on the CLR models for 109 ASD cases and their 1:1 matched TD controls
From: Blood manganese concentrations in Jamaican children with and without autism spectrum disorders
Quartile | n | MOR (95% CI) | P-value | |
|---|---|---|---|---|
