Finally, the longevity of the effect was investigated and the involvement of rhizosphere heat-tolerant antagonists of V. dahliae in the effectiveness of the method was examined.
In addition, the contact angle of water droplets was monitored for 70 hours to evaluate the longevity of the effect of plasma on zirconia surfaces.
They also speculated on the possible role of the antagonistic mycoflora of the soil in their effort to explain the longevity of the effect.
The longevity of the effect could be attributed to the near-eradication of the pathogen and to the well documented phenomenon of induced suppressiveness following solarization (4, 6, 7, 8, 9, 20).
Therefore, the longevity of the effect of OMT for LBP cannot be determined, and most of the included studies did not have a longer follow-up period for assessment of pain and functional status.
It is cautioned that this study cannot comment on the longevity of the effect of such an intervention and further work would need to be carried out to prove lasting efficacy.
Only one antigen-based immune intervention, the Diamyd GAD65 trial, has been shown to preserve residual insulin secretion in patients with recent-onset type 1 diabetes (20), and the longevity of the effect is still under follow-up observation.
In Study 2, the reliability and longevity of these effects were tested by replicating the intervention with a third measurement time-point.
