Meta-analysis on phenobarbital prior to preterm birth for
preventing neonatal periventricular haemorrhage

datasets

The following methods are implemented to evaluate how sensitive the results of a meta-analysis are to potential bias in meta-analysis and to support Schwarzer et al. (2015) <DOI:10.1007/978-3-319-21416-0>, Chapter 5 'Small-Study Effects in Meta-Analysis':

- limit meta-analysis by Rücker et al. (2011) <DOI:10.1093/biostatistics/kxq046>;
