16 Finally, variations in other design features (for example, length of follow-up and statistical power) could also contribute to mixed findings in this body of work.
Broadly, this may include such things as participant characteristics (for example, age, gender), intervention characteristics (for example, length, frequency, intensity, duration, mode) and outcome assessment methods (for example, type of instrument used to assess depression).
For other application areas, features can look completely different, as for example summarised in Lemke et al. (2009) for the area of time series forecasting, where features can include, for example, length, seasonality, autocorrelation, standard deviation and trends of the series.
Earlier studies reported that the effects of working hours were in operation in combination with, for example, length of rest break [ 18] and work flexibility [ 17] rather than alone.
For example, length changes of microsatellites within promoters and other cis-regulatory regions can also change gene expression quickly, between generations.
For example, length of CuNWs proposed in [29] was up to several millimeters, and many of CuNWs bundle together [29].
Also, the publication bias of some results, for example, length of mechanical ventilation, may affect the precision of this outcome.
The Mann-Whitney test was used for variables that were not normally distributed, for example, length of stay.
Both mean and median values were reported for continuous variables with skewed distributions, which were important in reporting resource use, for example length of ICU stay.
