SVAD Age Data: Angola

Description

The dental and skeletal age indicators were collected from anonymized radiographic images generated from a clinical context in Angola. All images were generated in the past ~10 years and include individuals between birth and 18 years of age. As part of the SVAD age indicator template, there are 64 age variables (columns) in the dataset, which include diaphyseal lengths and breadths, epiphyseal fusion/appearance of ossification centers, and dental development. However, because this data is collected from two dimensional radiographic images, only epiphyseal fusion/appearance of ossification centers and dental data are included; all diaphyseal dimensions have a 'NA'. The data collection methodology can be found in Stull and Corron (2022) and Corron et al. (2021), and the latter includes the abbreviations and full variable names along with its staging system.

Basic Key Code:

*DL_L/R == diaphyseal lengths

*DB_L/R == diapyseal lengths

*EF_L/R == epiphyseal fusion

*Oss == ossification 

*man_ and max_ == mandibular and maxillary dental development
