Inference has been limited, however, by data quality (e.g., drug and alcohol price information is subject to substantial error) and unobserved confounding (e.g., states that decriminalize marijuana may have generally less negative attitudes toward substance use).
All observational studies of the association between sugar or SSB intake and chronic disease risk factors have relied on self-reported measures of food intake, which are subject to substantial error and bias (16).
While a rare, serious complication could lead to a protracted illness, we felt that the problem of resolving the relative contributions of underlying and acute disease in these settings would introduce substantial error, and provide relatively little additional information.
Since this value is significantly below the time required for accumulation of the NMR spectrum, the value is subject to substantial error, and presumably represents an upper limit for the actual time constant describing interface formation.
We directly observed substantial errors in recognizing and referring severe illness and HSAs may not have recorded severe cases in registers because of lack of recognition and/or discomfort managing more severe cases.
This will mean further improvement of the global forest inventory and harvest statistics, which are currently subject to substantial errors due to infrequent and unequal sampling, and differences in definitions and classifications (FAO 2010).
