For this reason we could not test for the effects of (population level) heterozygosity and habitat in the same model, and thus had to drop heterozygosity from this second approach.
Loss of biodiversity and effects on population level were not detected at the examined concentrations, which were assumed to be environmentally relevant [129].
Conclusively, uncertainties will always remain, especially in terms of cumulative impacts and effects on population level.
The NICE Guidance provides a summary of the evidence in support of this harm reduction approach and also identifies a number of important gaps in the evidence including information on other nicotine delivery systems and the effect of population-level polices and interventions to support harm reduction.
Therefore, we undertook an ecologic study of hospital discharges for asthma in children from 0 (birth) to 19 years of age over the period 1983 2000 in the SoCAB to evaluate the effect of population-level O3 exposure on asthma-related hospital discharge over time.
We are currently extending our evaluation of the Alcohol Act to assess whether the reduction in population consumption we observed in this study translated into any positive effects on population levels of alcohol-related harms.
However, declining photosynthetic efficiency, a traditional physiological endpoint for photoautotrophs, was a good predictor of population level effects in phytoplankton.
The harvest plot is a novel and useful method for synthesising evidence about the differential effects of population-level interventions.
We present a method which we devised in the course of a systematic review of the effects of population-level tobacco control interventions on social inequalities in smoking.
The results were therefore synthesised using a combination of graphical and narrative methods, including the use of the Harvest plot, which is a useful graphical method for synthesising and displaying evidence about the differential effects of population-level interventions [ 32].
As part of a systematic review of the effects of population-level tobacco control interventions on social inequalities in smoking, we designed a novel approach to synthesis intended to bring aspects of the graphical directness of a forest plot to bear on the problem of synthesising evidence from a complex and diverse group of studies.
