The test stimulus was drawn randomly from class X for matching trials, and from class Y for non-matching trials.
LPM = (Σxi/n)/Σ (Σyi/n)/r where xi = limb matching trial RMSE for CVA group, yi = limb matching trial RMSE for HC group, n = # of limb matching trials, r = # of HC participants.
We used a cluster level model to analyse the trial data as this was the analytical model specified for the sample size formula 17 and is the method recommended by Hayes and Moulton 26 for pair matched trials with fewer than 15 clusters per arm.
A total of 43 pairs of matched trials were available for a paired analysis, with a pooled ratio of odds ratios of 1.38 (1.01 to 1.88, P=0.04).
However, smokers showed poorer accuracy on matched trials relative to nonmatched trials for smoking words on the 2- and 3-back tasks, which involve more effortful cognitive processing.
Test image orientation was randomized across trials in each block (each block was randomly composed by 48 match 12 non-match trials for each image orientation).
For trial 1, 3/6 variables were adequately matched; trial 4, 0/2; and trial 5, 3/6 variables were adequately matched.
For the matching trials, the instruction was p = 1, and the task was explained as equivalent to matching.
Participants then completed 15 practice force-matching trials at 10 % MVC for each of the three contraction types.
The NCI Molecular Analysis for Therapy Choice (MATCH) trial [NCT02465060] which screens for molecular features that may predict response to a drug with a given mechanism of action, is a multi-study, collaborative effort between the NCI and many pharmaceutical companies to begin to clarify the significance of molecular alterations in tumors not previously studied.
Across the full block of 80 trials there were two match trials and two mismatch trials for each morph set.
