$\cdot$ First is True because A systematic review attempts to gather all available empirical research by using clearly defined, systematic methods to obtain answers to a specific question. A meta-analysis is the statistical process of analyzing and combining results from several similar studies. So both are same;
$\cdot$ Second is wrong because sample studies determines casual relationship;
$\cdot$ Third is wrong because Qualitative data and quantitative data collection methods produce the different level of evidence. Even we can say that Quantitative data is more useful and have good estimates.)

Systematic reviews and meta-analyses are the same.
