If a rat did not consume the chocolate, a latency equal to the maximum trial length was recorded.
29 The P value was derived from the proportion of observations of the posterior distribution of the variance observed across time points within trials smaller than or equal to the variance within trials typically found in large osteoarthritis trials (0.01 for an effect size scale, 0.0625 for a 10 cm visual analogue scale).
As mentioned above, the block of the red dot task contained more trials to keep the number of trials without a red dot occurrence equal to the number of trials in the blocks of the standard and grey dots tasks.
In the attentional bias test, the number of trials in which the probe appeared in the position of the threat word was equal to the number of trials in which it appeared in the position of the non-threat word, so it should not have had an overall effect on processing of emotional information.
Both were compared with a chi-square distribution with degrees of freedom (df) equal to the number of trials minus one.
For DL, these are based on the normal distribution, whereas for the HKSJ method, they are based on the t-distribution with the degrees of freedom equal to the number of trials minus one, and a weighted version of the DL standard error.
In other words, the series of Poisson trials can be replaced by two sets of Bernoulli trials with trial probabilities p1 and p2 constructed such that the variance is equal to the original set of trial probabilities.
Therefore, we will also calculate the proportion of patients who have benefited, that is, demonstrated improvement greater than or equal to the MID in each trial, then aggregate the results across all studies.
The weight for each trial was equal to the inverse of the sum of the within-trial variance and the residual between-trial variance, in order to correspond to a random-effects analysis.
