帮忙看看这几句英文,翻译通顺
Although the NSCH uses a random sample design, the survey process does not ensure that all types of neighborhoods were represented or that a specified number of individuals residing in each type of neighborhood were included in the data. As well, given data structure, factors impacting selection into neighborhood residence were not able to be addressed in the current analyses. The data are cross-sectional; thus the study design does not allow for establishment of cause and effect relationships. The overall response rate for the survey was 46.7%. Weighting of data facilitated adjustment for the potential bias of differential response rate and interview completion.
