A 2010 study in the UK confirmed a positive effect on accountability, but not necessarily on trust in government.
Overall, the results confirmed a positive effect of qTSN4 on panicle spikelet number, which in turn was correlated with the main stem growth rate during panicle development.
Indeed, in the review [1], there are several references confirming a positive effect of nano-Se on the GSH-Px activity.
The analysis did not confirm a positive effect of G-CSF on the reduction of infected wounds rates.
The treatment with erlotinib alone had a similar effect, while the simulations just confirmed a positive effect of pertuzumab (Table 1).
An open-label trial is insufficient to confirm a positive effect of lactobacilli on caries prevention because placebo effects were evident in previous double-blind trials [ 7, 9, 10].
In our previous studies we confirmed a positive effect of He-Ne, GaAlAs, and AlGaInP laser irradiation at a dose of 3 J/cm and 5 J/cm on primary and secondary wound healing [ 14, 27, 28, 33, 35].
Two other studies (Ducker et al. 2013; Hobson et al. 2013) have independently confirmed a positive effect of 4 weeks of β-alanine supplementation (~80 mg kg−1) on 2000-m rowing performance with similar gains in each case.
The most attractive target engagement and efficacy biomarkers are those in which changes occur early after the interaction of the drug with its target, and whose expression reflects the immediate downstream effects of target engagement, confirming a positive effect of therapeutic intervention.
Although several studies have suggested that physical exercise may be beneficial to the speed of recovery of patients with depression and chronic fatigue disorder, we could not confirm a positive effect of a structured physical exercise programme on the perceived quality of life of patients with stress-related mental disorder [ 8, 18, 19].
