But with most diseases, the findings have explained only a small part of the risk of getting the disease.
As recently as 2008, for instance, Robert Lawrence of Harvard, one of the country's most respected trade experts, concluded that trade explained only a small share of growing income inequality and labor market displacement in the United States.
Systemic factors explained only a small part of the increased prevalence.
With R 2 = 0.163 the regression model explained only a small proportion of total variation [8].
Thus, including "Perception of Instructor" and "Independence" as predictors explained only a small amount of variation in students' likelihood of talking to instructors.
The high heritability of BD is well established; however, identified susceptibility genes have so far explained only a small proportion of the risk (McGuffin et al. 2003; Farmer et al. 2007; Gottesman et al. 2010).
Seasonal temperature patterns were also positively correlated with disease abundance, but explained only a small portion of the variance.
Differences among sites, which were modeled with a random intercept, explained only a small fraction (∼3%) of the total variance in clutch size.
Reassuringly, final regression models for SF-36 vitality were similar, and importantly, all explained only a small amount of variance in fatigue.
Although the number of hours spent playing per week explained only a small percentage of the variance observed, it was a significant predictor of perceived time, with those who played the most making less accurate time estimates.
Although both, BMI and weight are highly heritable, the variants detected in these large GWA studies explained only a small fraction of the inherited variability in BMI and weight [7], [8].
