In order to control for activations unspecific to planning, two control conditions were presented, which were matched for the length of single events in the ToL task.
We created an unbiased geometrical average image template for each of the three groups, which were matched for sex and age (mean age: 76.1 years+/- 7.7 SD).
The control group, which was matched for age, sex, body mass index (BMI), racial and socioeconomic status, family education background and time missed at school, was composed of 79 healthy children (27 males and 52 females), attending a state school in the same geographic area.
In the present study we had the unique opportunity to compare the level of HIV-1 specific CD8+ T-cell polyfunctionality between these two cohorts which were matched for viral burden.
Due to the large sample size, the detailed clinical and neurobiological characterization and the control group, which was matched for age, gender and either living surroundings or workplace (as very rough proxies for EMF-exposure), this study population [25] was well suited to investigate the relationship between tinnitus, subjective electromagnetic hypersensitivity and EMF-exposure.
Retinal and cerebellar RT-PCRs [77] were performed in 1X MasterAmp™, with equal molar ratios of competing forward primers (1 nM) and a single fluorescent (6-FAM) reverse primer (LP4) as indicated (Table S2), which were matched for length and G+C content.
Figure 4 shows the results for different µa and µs´, which are matched for both layers.
The same covariates were included, except for age, which was matched for each twin pair by definition.
Cause of death was compared with mortality statistics from the ONS, which were matched for age, sex and geographical location.
However, this reduction was not significant compared with their controls, which were matched for age, BMI and baseline MD [ 42].
We also enrolled 189 genetically unrelated subjects having normal spirometric values and no respiratory symptoms which were matched for sex and similar ethnicity origin with the patients.
