A New Method to Interpret Cluster Analysis Results in the Presence of Heterogeneous Clusters.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Contrary to several other statistical analyses (ANOVA, linear regression, etc.) normality is not a requirement of cluster analysis (CA). However, certain types of departure from normality, such as high skewness, can cause problems in CAs. In such cases the proportion of extreme cases will increase, increasing the chance to obtain heterogeneous clusters. The aim of the paper is to propose a new method for interpreting CA results in the presence of heterogeneous clusters. After performing CA, all cases are classified as either typical or atypical, depending on how close they are to their own cluster center (cluster centroid). A key concept is a new variable that measures the distance of each case to its own cluster centroid. A case is considered typical if this distance does not exceed a predetermined threshold, and atypical if it does. Typical cases can be used to provide a robust estimation of the cluster centroids. Additionally, analyzing subgroups of atypical cases within clusters where they reach an interpretable proportion can refine the explanation of cluster profile. The usefulness of the new method is demonstrated using four parental attachment variables of avoidance and anxiety, where high skewness and therefore heterogeneous clusters are anticipated. The study sample consisted of 918 young adults aged between 20 and 35. Standard hierarchical and
