<h3>BACKGROUND:</h3> Most randomized controlled trials (RCTs) and meta-analyses of RCTs examine effect modification (also called a subgroup or interaction), in which the an intervention varies by another variable (e.g., age disease severity). Assessing credibility apparent presents challenges; therefore, we developed Instrument for assessing Credibility Effect Modification Analyses (ICEMAN). <h3>METHODS:</h3> To develop ICEMAN, established detailed concept; identified candidate...

Calretinin (CR)-expressing periglomerular (PG) cells are the most abundant interneurons in glomerular layer of olfactory bulb. They predominately generated postnatally from septal and dorsal subventricular zones that continue producing them well into adulthood. Yet, little is known about their properties functions. Using transgenic approaches patch-clamp recording mice both sexes we show CR(+) PG origin have homogeneous morphological electrophysiological properties. However, unlike other...

The association between periodontitis and atherosclerotic cardiovascular diseases (ACVD) has been established in some modestly sized studies (<10 000). Rarely, however, studied directly; often tooth loss or self-reported used as a proxy measure for periodontitis. Our aim is to investigate the adjusted ACVD among all individuals registered large dental school Netherlands (Academic Centre Dentistry Amsterdam (ACTA)).Anonymised data were extracted from electronic health records patients aged...
