In general, in the irradiated plastic samples, bacterial abundance reached higher values (Fig. 2c, d) than in the irradiated control without plastic but in some cases, the differences were low or not significant (t test, p < 0.05; Fig. 2a, b, e, f).
For most medications, there were poor agreements for co-payments, though mean differences were low (< $4.26 for all but paracetamol).
SSF with fine gravel produced effluents of better quality than those with coarse gravel; the differences were low in comparison to the effect of water depth and HLR.
The biologic relevance (whether this reflects a treatment effect) is not clear as the differences were low in absolute numbers mainly because of the low baseline expression in many of the tumors.
Previous studies reported an increase of upper body mass index (BMI) quantiles for formula fed infants compared to breastfed infants, while corresponding mean differences were low.
The dimorphic muscles in castrated males with testosterone replacement (T+) achieved higher forces and lower fatigability than did castrated males without replaced testosterone (T0 males), but the magnitude of the differences was low and many of the pair-wise comparisons of each muscle property were not statistically significant.
Ethnic differences were not statistically significant, however the power to detect differences was low.
Our statistical power to find such differences was low.
Very few other gender-related differences were seen, although power to detect such differences was low.
Therefore, the risk of false-positive detection due to probe-type differences is low.
