Summary
Brief summary
The primary purpose of the study is to determine whether providing a single high dose of vitamin D using in conjunction with standard treatment (including antibiotics) improves outcomes in adults hospitalised with pneumonia. The main hypothesis is that outcomes will be improved in those taking vitamin D compared to those who are given a placebo.

The data sets have sufficient data for re-analysis and also inclusion in future meta-analyses including all blood/biochemical measurements, chest x-ray findings, and some basic demographic details. However, the data sets have been amended to exclude any data that could lead to participant identification and are de-identified.
When will data be available (start and end dates)?
Data is immediately available following publication; no end date has been determined
