NA = this estimate is not applicable for that particular cell Across the trials, arithmetic mean, geometric mean, and average AUC produced very similar scores, and the maximum score was considerably higher than the other scores (see M rows in Table 1).
Sixteen trials reported egg counts as geometric mean egg counts, four trials as arithmetic mean egg counts, three trials reported both.
For the alternative measure of threat vigilance, we predicted that worry would result in faster responses to probes in the attended location than mental arithmetic on trials containing threat words, regardless of the location of the threat word, but not on trials containing only neutral words.
This imbalance had the purpose of maximizing the number of trials useful for assessing our hypotheses (matching trials are irrelevant to assess arithmetic relatedness and distance effects) and allowed us to obtain a potential of 90 data points for each critical cell of the design.
To enable comparison of our data with other alcohol intervention trials we also report the arithmetic mean in the text, as this measure has often been used in reporting trial data despite the presence of skew in the data [10].
These trials, not relevant for addressing arithmetic relatedness and distance effects, also included five categories.
As hypothesized for the alternative operationalization of threat vigilance, the faster response times for worry than arithmetic reported above for threat trials were not present for neutral trials, t 55) = 0.00, p = 0.997, d = 0.00 (Figure 1).
We obtained the unit time to solve (7) by calculating the arithmetic mean from 100 trials.
As a control measure for the stability of the small (n < 40) trials results, we substituted reported SDs (or other variance data) with the arithmetic mean SD from the other trials with the same intervention if SD was lower than the the arithmetic mean [ 26].
Significant negative correlations with CTG-repeat expansion size were found on tests associated with executive function (WCST, CWT B and TMT B), arithmetic (Arithmetic), visuospatial construction (RCFT, copy trial), speed and attention (TMT) and verbal ability (Vocabulary and Comprehension).
