7.) Project description:
The neurotoxicity of lead is well-known and even low exposure levels potentially impact neurocognitive abilities. This meta-analysis aimed to investigate associations between neurocognitive performance and lead exposure in adults and further assess potential effect thresholds. Articles indexed in Medline published until January 2017 reporting associations between lead exposure, blood lead, cognitive abilities and sensomotoric performance were included. The unbiased, standardized mean differences g between lead exposure and control groups extracted from the primary studies were pooled using a three-level, random-effects meta-analytic model with a restricted maximum likelihood estimator. Moderator analyses were conducted using weighted, mixed-effects regression analyses.
