Validation and comparison study of three urbanicity scales in a Thailand context.
Article in BMC public health, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundValidity and reliability of an urbanicity scale is of utmost importance in developing effective strategies to minimize adverse social and health consequences of increased urbanization. A number of urbanicity scales for the quantitative assessment of the "static" feature of an urban environment has been invented and validated by the original developers. However, their comparability and robustness when utilized in another study context were not verified. This study aimed to examine the comparability, validity, and reliability of three urbanicity scales proposed by Dahly and Adair, Jones-Smith and Popkin, and Novak et al. in a Thailand context.
methodsUrban characteristics data for 537 communities throughout Thailand were obtained from authoritative sources, and urbinicity scores were calculated according to the original developers' algorithms with some modifications to accommodate local available data. Comparability, dimensionality, internal consistency, and criterion-related and construct validities of the scores were then determined.
resultsAll three scales were highly correlated, but Dahly and Adair's and Jones-Smith and Popkin's were more comparable. Only Dahly and Adair's scale achieved the unidimensionality assumption. Internal consistency ranged from very poor to high, based on their Chonbach's alpha and the corrected item-scale correlation coefficients. All three scales had good criterion-related validity (when compared against the official urban-rural dichotomy and four-category urbanicity classification) and construct validity (in terms of their relation to the mean per capita monthly income and body mass index).
conclusionsThis study's results ensure the utility of these three urbanicity scales as valid instruments for examining the social and health impacts of urbanicity/urbanization, but caution must be applied with comparisons of urbanicity levels across different studies when different urbanicity scales are applied.
