Affective and non-affective psychoses show rural-urban variation By Lucy Piper, Senior medwireNews Reporter Rates of affective psychosis appear to be increased in even more urbanised areas, study results from France display. The results also confirm previous observations of increased prices of non-affective psychosis with urbanisation. The researchers compared the prices of psychosis between an rural and urban catchment region, based on 2 years of data collected from the majority of practicing psychiatrists.This analysis was retrospective and exploratory in nature and for that reason subject to limitations. The alpha mistake for hypothesis testing was allocated to the principal analysis previously, 2 and RAS and BRAF status may not be representative of the intention-to-treat population from the original randomization. However, methodologic aspects of the analysis offered a rigorous framework for analyzing RAS and BRAF as biomarkers. Tissue samples were gathered with appropriate informed consent before randomization. The biomarker hypothesis was restricted to RAS and BRAF, and the statistical evaluation program was finalized before RAS and BRAF status became available. In addition, the analysis was conducted with data from a big, randomized, controlled trial.2 The higher rate of ascertainment of RAS status minimized the potential for ascertainment bias.
