There is a small but marginally significant difference (p = 0.02, t-test) between the mean copy number of the Ethiopian HIV-only and the HIV-TB co-infected cohort, although this is not replicated in the smaller Tanzanian cohort (p = 0.69).
Children who have experienced a longer duration of maternal migration during their lifetime were less likely to be assessed as performing better than their peers at school by their caregivers, but this is not replicated for child self-report of school performance.
In summarizing these results, while we found some striking differences, for example with coding sequence length in brain, we note that this was not replicated in lymphocytes.
Martin and colleagues demonstrated that the -336G allele was associated with susceptibility to parenteral but not mucosal HIV-1 infection, although this was not replicated in individuals of recent African descent [31].
Losses at 4q and 18q were found to be associated in one study [9] but this was not replicated in a recent analysis [10], which identified 7 CNA associations and 6 anti-correlations.
Rs3793784 conferred a small increase in risk for late AMD in the Dutch population (The Rotterdam and AMRO-NL study), but this was not replicated in two non-European studies (AREDS, Columbia University).
This was not replicated in another model comprising age and stage of disease.
It has been reported to be reduced in amplitude in people with ADHD [ 125- 127], although this was not replicated in two further reports [ 128, 129].
In both pilot studies [ 27, 28] improved executive control was observed using neuropsychological tasks, but this was not replicated in the two randomised controlled trials.
In addition, accumulation of transcripts harboring the expanded G4C2 repeat in nuclear RNA foci was described [ 33] although this was not replicated in another study [ 146].
They reached statistical significance after adjusting for baseline covariates, but this was not replicated when adjusting for the predictive risk score.
