“closely approaches the brink of significance”

Also there were several of parameters closely approaches the brink of significance: mass flow rate between Sect. 15 and 16 (group 2c: 4.70 ± 0.001; group 2d: 2.60 ± 0.001; p = 0.07); the maximum velocity in cross Sect. 13 (group 2c: 9.45 ± 1.230; group 2d: 17.89 ± 4.230; p = 0.06), Sect. 16 (group 2c: 15.55 ± 2.790; group 2d: 9.05 ± 1.854; p = 0.08).
