The square drawing test (SDT) is vertical writing test, conducted to evaluate equilibrium, done with the subject blindfolded. We investigated the development of equilibrium and presbyastasis by using SDT. Fifty three children underwent SDT every year for nine years (5-14 years old). Sixty six healthy elderly subjects (65-88 years old) were also examined. Control results were obtained from 117 y...

BACKGROUND AND PURPOSE The Four Square Step Test (4SST), a quick and simple test of multidirectional stepping, may be useful in predicting falls in people with Parkinson disease (PD). We studied the reliability of the 4SST and its ability to discriminate between freezers and nonfreezers, between fallers and nonfallers, and factors predictive of 4SST performance in people with PD. METHODS Fift...

Applied researchers have employed chi-square tests for more than one hundred years. This paper addresses the question of how one should follow a statistically significant chi-square test result in order to determine the source of that result. Four approaches were evaluated: calculating residuals, comparing cells, ransacking, and partitioning. Data from two recent journal articles were used to i...

Here we show that the one-sided chi-square test used for evaluating the significance of the overlap between the RH network and other existing datasets and the Bayesian loglikelihood score (LLS) approach used for integrating diverse datasets [1,2] are closely related. The Fisher’s exact test was used instead of the chi-square test when the expected value in a cell of the contingency table was ≤ ...

BACKGROUND Malnutrition, especially under nutrition puts children at increased risk of morbidity and mortality and remains a serious barrier in child growth, development and survival. This is a major public health problem among under- 5 children in Nepal particularly in rural areas. OBJECTIVE To assess the burden and contributing factors for malnutrition in hill community of Ilam district in ...

OBJECTIVE To investigate the relationship between the increase of body mass index and the prevalence and severity of asthma in adolescents from Santa Maria, in southern Brazil, and surrounding regions. METHOD A cross-sectional, observational, population-based study was carried out with 4,010 schoolchildren aged 13 and 14 years, without any gender restrictions, who answered the written questio...

Febrile seizure is a common disorder between children with age of 6 month to 6 years and its recurrence is an emotional trauma for parents. Causative factors of febrile seizure have not been completely identified. In this study we determined the correlation between causative factors and probability of febrile seizure occurrence. This study was performed on 344 children factors related to febril...

Chi-square tests are generally used for distinguishing purposes; however when they are combined to simultaneously test several independent variables, extra notation is required. In this study, the chi-square statistics in some previous works is revealed to be computed half of its real value. Therefore, the notion of Multi–Chi-square tests is formulated to avoid possible future confusions. In or...
