Even when he adjusted his data to take into account the biases that come with age, gender, educational qualification and religion, Perales still found that there was a "large and statistically significant" association between cognitive ability and support for the equal rights of same-sex couples.
There was no evidence of significant difference regarding cognitive ability and motor disability between the conventional treatment and ECMO groups.
Here, we found a significant association between cognitive ability according to the MMSE and health literacy assessed with the BHLS.
This hypothesis is further supported by the findings that postoperative delirium is associated with a significant decline in cognitive ability during the first year after cardiac surgery.
Adjusting for age and NARTIQ, there was no significant change in cognitive ability over time (F4,254.0 = 1.85, p =.12), nor in differential change in cognitive ability between cognitive tests over time (F20,226.0 = 1.06, p =.39).
13 In the current study, no significant difference in cognitive ability was observed according to living status, which was in line with the results of some previous dementia studies.
The US Food and Drug Administration has defined an improvement of at least four points in the ADAS-cog score as clinically significant (reported in [ 27, 28]), and a MMSE change of three points has been suggested to indicate a clinically significant alteration in cognitive ability [ 29, 30].
Discussing his findings in The Conversation on Tuesday, Perales explains how he found there to be a "strong and statistically significant association between higher cognitive ability and a greater likelihood to support equal rights between same and different sex couples".
To put these results in context, levels above 10 µg/dL in blood have had clearly documented significant negative effects on cognitive ability in children [34] [35].
No significant differences in age, cognitive ability or number of concomitant medications at baseline were found between genders.
In a study by Burdick et al. [ 49], this SNP was also the only one that showed a significant effect on general cognitive ability in patients and controls.
