There have also been reports of reduced effectiveness of peripheral programmes such as in a study in China that showed that village clinics and township health centres were less likely to achieve viral suppression compared to county-level hospitals [ 14].
The higher rates of dose escalation, discontinuation, switching, shorter dosing intervals, and shorter time to discontinuation among patients previously exposed to anti-TNF therapy are suggestive of reduced effectiveness or poorer tolerance of subsequent anti-TNF agents after failure of the initial anti-TNF therapy.
Finally, it is vital to recognize that insecticide resistance is not the only cause of reduced effectiveness of vector control tools.
The estimates of reduced effectiveness were applied under two sets of assumptions: full reduction and part reduction.
This estimate takes no account of reduced effectiveness in those at work despite being in a migraine attack (presenteeism).
Furthermore, the result has since been contradicted by a meta-analysis of data from 16,570 subjects, which found the T allele of the same SNP to be associated with reduced effectiveness of statins in preventing MI.
It appears there is a reduced effectiveness of the antitumour actions of tamoxifen, possibly because of developing drug resistance, but also an increase in oestrogenic side effects such as endometrial cancer and blood clots.
"The concern must be that the reduced effectiveness of these antibiotics may force clinicians to turn to alternative agents which may be less effective, or have more side-effects, in a potentially vulnerable patient group," added Jamieson.
Values lower than 0.83 suggest that plants are growing under stress and that PSII reaction centers are damaged which, in turn, is connected with reduced effectiveness of electron transport (Basu et al., 1998) when plants are grown under salinity.
