In this task, you are given an abstract of article. Your task is to generate label "True" if abstract is structured, otherwise generate "False". A structured abstract is composed of a topic sentence (or key sentence), relevant supporting sentences, and a closing (or transition) sentence. This structure is key to keeping your abstract focused on the main idea and creating a clear and concise image.

Input: Consider Input: OBJECTIVE Chronic physical comorbidity is common in dementia. However, there is an absence of evidence to support good practice guidelines for attention to these problems. We aimed to study the extent of this comorbidity and its impact on cognitive function and disability in population-based studies in low and middle income countries, where chronic diseases and impairments are likely to be both common and undertreated.
METHODS A multicentre cross-sectional survey of all over 65 year old residents (n = 15 022) in 11 catchment areas in China, India, Cuba, Dominican Republic, Venezuela, Mexico and Peru. We estimated the prevalence of pain, incontinence, hearing and visual impairments, mobility impairment and undernutrition according to the presence of dementia and its severity, and, among those with dementia, the independent contribution of these impairments to cognitive function and disability, adjusting for age, gender, education and dementia severity.
RESULTS Incontinence, hearing impairment, mobility impairment and undernutrition were consistently linearly associated with the presence of dementia and its severity across regions. Among people with dementia, incontinence, hearing impairment and mobility impairment were independently associated with disability in all regions while the contributions of pain, visual impairment and undernutrition were inconsistent. Only hearing impairment made a notable independent contribution to cognitive impairment.
CONCLUSIONS There is an urgent need for clinical trials of the feasibility, efficacy and cost-effectiveness of regular physical health checks and remediation of identified pathologies, given the considerable comorbidity identified in our population based studies, and the strong evidence for independent impact upon functioning.

Output: True

Input: Consider Input: Circadian oscillators play an indispensable role in the coordination of physiological processes with the cyclic changes in the physical environment. A significant number of recent clinical and molecular studies suggest that circadian biology may play an important role in the regulation of adipose and other metabolic tissue functions. In this discussion, we present the hypothesis that circadian dysfunction may be involved in the pathogenesis of obesity, type 2 diabetes, and the metabolic syndrome.

Output: False

Input: Consider Input: The geographic ranges of ticks and tick-borne pathogens are changing due to global and local environmental (including climatic) changes. In this review we explore current knowledge of the drivers for changes in the ranges of ticks and tick-borne pathogen species and strains via effects on their basic reproduction number (R 0), and the mechanisms of dispersal that allow ticks and tick-borne pathogens to invade suitable environments. Using the expanding geographic distribution of the vectors and agent of Lyme disease as an example we then investigate what could be expected of the diversity of tick-borne pathogens during the process of range expansion, and compare this with what is currently being observed. Lastly we explore how historic population and range expansions and contractions could be reflected in the phylogeography of ticks and tick-borne pathogens seen in recent years, and conclude that combined study of currently changing tick and tick-borne pathogen ranges and diversity, with phylogeographic analysis, may help us better predict future patterns of invasion and diversity.
Output: False
