First, we did not find effects on all dependent variables.
The presented studies generally do not find effects even at high concentrations.
Also, we did not find effects of diet on body temperature during torpor, or its duration.
Studying a program in Nicaragua, Barham et al. (2013) find effects after 10 years on educational attainment and test scores.
Although they find effects in the expected direction, their size is modest in general but increases with education.

Equatorial magnetometer data from the Magnetic Data Acquisition System/Circum-pan Pacific MAGDAS/CPMNr Network (MAGDAS/CPMN, 1 s) (Yumoto and the MAGDAS Group, 2006) and SuperMAG (1 min) were also used to find effects of penetration electric fields.
Whilst in vitro studies did not find effects of the G2677T/A SNP [11, 12], another study showed an association with decreased Pgp expression in the human placenta [13].
In addition, we did not find effects of reduced oral exposure to salt over weeks, through the sodium-reduced diet, on salt taste preferences, in contrast to earlier studies.
