Note(s): Partial sequential mediation (20%<variance accounted for (VAF)<80%)^***

Total direct and indirect effects were estimated using control variables, such as age, sector and size, which affect SP. Coefficient, t-statistics, p-values and percentiles were determined by a percentile bootstrap confidence interval of 90% (one tail) based on n = 10,000 subsamples
