Assessment of cardiorespiratory consequences of sleep apnoea syndrome (SAS) is difficult owing to confounding factors, especially obesity, that are strongly associated with SAS. This study was designed to assess the cardiorespiratory consequences of SAS by comparing the results of a comprehensive cardiorespiratory evaluation in apnoeic and nonapnoeic patients with massive obesity. In a retrospe...

SAS/GRAPH is a powerful tool for customizing the box plot to detect and identify outliers. This paper shows how to use the ANNOTATE facility and annotate data set to customize box plots and profile plots of outliers using data from a dietary-health study. This paper assumes: • A working knowledge of basic SAS/GRAPH procedures. • The ability to display or print graphics on your operating system...

BACKGROUND Simpson-Angus Scale (SAS) is an established instrument for neuroleptic-induced parkinsonism (NIP), but its statistical properties have been studied insufficiently. Some shortcomings concerning its content have been suggested as well. According to a recent report, the widely used SAS mean score cut-off value 0.3 of for NIP detection may be too low. Our aim was to evaluate SAS against ...

BACKGROUND The Survey of Autonomic Symptom (SAS) scale was reported as an easy instrument to assess the autonomic symptoms in patients with early diabetic neuropathy. In this study, we investigated the relationship between the SAS scale and the parameters of cardiac autonomic neuropathy (CAN) in Korean patients with diabetic peripheral neuropathy (DPN). METHODS The SAS scale was tested in 30 ...

The mechanisms that ensure centrosome duplication are poorly understood. In Caenorhabditis elegans, ZYG-1, SAS-4, SAS-5 and SPD-2 are required for centriole formation. However, it is unclear whether these proteins have functional homologues in other organisms. Here, we identify SAS-6 as a component that is required for daughter centriole formation in C. elegans. SAS-6 is a coiled-coil protein t...

This paper describes the design and implementation of a large SAS production billing system developed at Hewlett-Packard's Corporate Data Center. The design considerations for implementing such a large system in SAS will be discussed along with advantages of implementing this system in SAS, such as: quick prototyping and implementation, ease of use, adaptability, efficiency and the additional f...

BACKGROUND Congenital subaortic stenosis (SAS) has a high recurrence rate after surgical correction. Aortic valve disease frequently coexists with SAS, being its occurrence and progression unpredictable. We aimed to assess predictors of SAS recurrence and aortic valve disease occurrence and progression. METHODS Retrospective analysis of 51 patients with SAS followed in a congenital heart dise...

Researchers in the EDM community have always relied on sophisticated tools to analyze data and build models. As the amount of data that can be collected and stored grows, the need for tools capable of handling “big data” becomes ever more prevalent. SAS Analytics U is a new initiative for making SAS data analysis and mining tools available for free to educational researchers and instructors. Th...

In recent years, the class of generalized linear models has gained popularity as a statistical modeling tool. This popularity is due in part to the flexibility of generalized linear models in addressing a variety of statistical problems and to the availability of software to fit the models. The SAS system provides two new tools that fit generalized linear models. The GENMOD procedure in SAS/ST...

The SAS Metadata Server® introduces a new world to clinical data programmers. It is a storage centre to store information about every single object there is in the SAS System®. Not only the table level and column level attributes such as SAS table labels and column lengths, extended attributes are also built in and extensible to keep valuable business data in this centralized location. To acces...
