Summary
| Description | English: This forest plot shows trials of the use of corticosteroids to hasten lung development in pre-term babies. It is an iconic illustration of the power of medical reviews to save lives. The iconic review is from the 1980s, so this plot does not contain all the evidence of the up-to-date version of the same review.
This data is the data from which the logo for Cochrane (organisation) is derived. |
