Geometric Method and Generalized Linear Models. Two Opposite Multiparametric Approaches Illustrated on a Sample of Pituitary Adenomas

We used two statistical methods to identify prognostic factors: a log-linear model (logistic and COX regression, based on the notions of linearity and multiplicative relative risk), and the CORICO method (ICOnography of CORrelations) based on the geometric significance of the correlation coefficient. We applied the methods to two different situations (a "case-control study' and a "historical cohort'). We show that the geometric exploratory tool is particularly suited to the analysis of small samples with a large number of variables. It could save time when setting up new study protocols. In this instance, the geometric approach highlighted, without preconceived ideas, the potential role of multihormonality in the course of pituitary adenoma and the unexpected influence of the date of tumour excision on the risk attached to haemorrhage.

Young helpline callers and difference: exploring gender, ethnicity and sexuality in helpline access and provision

This article, which has its origin in a feasibility study carried out for three youth telephone helplines, focuses on gender, difference and helpline access by young people. During the research process the writers noted that for the three commissioning helplines, as is the case with the majority of other telephone helplines, approximately two‐thirds of callers are female. A helpline for young Muslims where the gender access ratio was 50/50 stood out as being different in this respect. Until recently, literature on gender and help‐seeking has tended towards making a blanket identification of males as experiencing difficulties in negotiating pathways to help. Although this difficulty of males is evident in relation to both help‐seeking and access to helplines, our study suggests that, at least in relation to helpline usage, when we take culture, ethnicity and sexuality into account, the help‐seeking situation may be more nuanced. This has implications in terms of enabling a cross‐section of young people to access helplines as well as with regard to helpline service development.     

On pooling data summaries in the absence of interactions “response-by-study”

The standard hypothesis testing procedure in meta-analysis (or multi-center clinical trials) in the absence of treatment-by-center interaction relies on approximating the null distribution of the standard test statistic by a standard normal distribution. For relatively small sample sizes, the standard procedure has been shown by various authors to have poor control of the type I error probability, leading to too many liberal decisions. In this article, two test procedures are proposed, which rely on thet—distribution as the reference distribution. A simulation study indicates that the proposed procedures attain significance levels closer to the nominal level compared with the standard procedure.
