Analysis of variance models were used to study the effects of 'Treatment' and 'Experimental plot' (nested in treatment) or 'Treatment' and 'Soil water potential' as a continuous covariate on the growth characteristics.
Results from logistic regression models with water arsenic modeled as a continuous and categorical exposure are shown in Table 3.
We performed linear regression analyses of the village data using Excel (Microsoft Corp., Redmond, WA) least-squares analysis with the village SMRs as dependent observations and with median village well water arsenic level as a continuous predictor.
Also, when the model was assessed with tap water nitrate levels as a continuous variable, there was no statistically significant association found with methemoglobin levels and nitrate levels at 36 weeks gestation among women who drank tap water at home (β = 0.787, p = 0.086).
The oil-in-water emulsions behaved as a continuous phase to the added solids.
Pigeons also are distinctive in their unusual manner of drinking, in which water is sucked in as a continuous draft, the process being assisted by muscular contractions of the esophagus, whereas other birds take a sip of water and then tip back the head to swallow.
When total water intake was examined as a continuous measure (per 20 ounce/day increased intake), the adjusted increase in mean birth weight was 7.3 (95% CI: -0.8, 15.5) grams.
This paper investigates the suitability of a number of potential crystallisation models to best describe the experimentally observed behaviour of the antisolvent crystallisation of benzoic acid from aqueous ethanol solution using water as an antisolvent, in a continuous plug flow crystalliser.
For example, Byrne (2003) estimated average trichloroethylene levels and MCL exceedances in drinking water systems and characterized exposure as a continuous measure across San Joaquin County; the community level, however, is more appropriate when considering community-level exposure.
We analyzed cumulative years in the water district as both a continuous and categorical variable.
