The removed trial-level data were evenly distributed across trials.
We also removed trials that potentially contained non-neuronal (e.g. movement, electrical) artefacts.
The method removes the smaller trials causing funnel plot asymmetry, use the 'trimmed' funnel plot to estimate the true 'centre' of the funnel, and then includes both the removed trials and their 'missing' counterparts around the centre.
However, for comparability with the results for the vaginal delivery outcome, the results we report here are those from the random effects sensitivity analysis, having removed trials at high risk of bias (160 trials included).
Nevertheless, subgroup analyses were conducted for both vaginal delivery and caesarean section outcomes, in which we removed trials which had randomized women with previous caesarean section (either all or some participants).
But the Ministry of Justice played down reports of a review of trial procedures, saying: "There are no plans to remove trial by jury.
After removing Trial Identification information, track files were renamed to provide this information (i.e., "Control1side.xlsx").
Figure 2 depicts examples of No-change, and, and Remove trials.
Thus, the peri-stimulus time histogram reduces temporal precision through binning, and the central spike train removes trial-to-trial structure by representing the collection as a single spike train.
In addition, the gaze position coordinates were calculated relative to the sample dot locations and the central cross with the aim to remove trials in which observers departed from instructions.
After removing trials with errors and artifacts, an average of 121 trials (SD = 23) per participant were entered in analyses.
