The ash content in dry avian bone mass is a variable which depends on the age of individuals, bird systematic position and environmental factors, including the supply of F− in the diet (Chan et al. 1973; Bird et al. 1992; Lundy et al. 1992; Shim et al. 2011).
The successful implementation of an ISS system in Sierra Leone was the result of many factors, including a systematic approach, national ownership, appropriate timing, and external support.
On the other hand, in a systematic survey of cardiovascular risk factors, including electrocardiograph abnormalities, congestive heart failure and cardiomegaly by imaging and autopsy studies, there was no increased frequency of these findings in HSD compared to age-matched controls without HS [ 12].
This systematic review demonstrated the importance of considering human factors including the influence that different stakeholders have on the success or otherwise of the implementing a CCM.
Systematic efforts have been made to account for several factors, including: forest type, stand age, region, and product type [15].
Unlike the mean differences presented in Table 1, which do not account for confounding factors, these ATT estimates account for the other confounding factors including selection bias arising from potential systematic differences between participants and non-participants.
Systematic efforts have been made to account for several factors, including: forest type, stand age, region, and product type [ 15].
A systematic review published in 2010 summarized the epidemiologic evidence on behavioral factors, including tobacco, alcohol, and illicit drug use, and physical, sexual, and occupational activity.
Systematic reviews attribute the wide range of prevalence rates to a number of factors, including small samples, variation in assessment tools used, and classification of symptoms [ 6, 7].
These systematic deviations from the model are found to be influenced by a variety of factors, including both design and operating features.
