2008	0.57 ± 0.18**	0.22 ± 0.51^b,c
2009	0.43 ± 0.37*	−2.13 ± 0.94^b

Note: In the case of (a) strikes (pork), the statistically significant differences between slopes for the strike year 2010 and the other years are marked with asterisks. In the case of (b) global market price spikes (food oil), the statistically significant differences between the years with the highest (2008, 2011) and the lowest (2006, 2009) FAO food price indices are marked with the same character. The Westfall method was applied for the pairwise comparisons (Westfall, 1997). (^o) p < 0.10, (*) p < 0.05, (**) p < 0.01, (***) p < 0.001.
