In a qualitative systematic review it is usually a synthesis of qualitative material of studies. There are different methods thinkable as in qualitative research. It depends on your objectives. What exactly do you want to know? What kind of review are you planning? A detailed description of a thematic synthesis as an example is available in our article 'Criteria for evaluating transferability of health interventions: a systematic review and thematic synthesis'. Hope this helps.

Hi Praven,

Systematic literature reviews, assuming a quantitative epistomology, are best done thematically. However, from a qualitative perspective, you could use either of the two.
