Out of 385 selected studies were 9 included and applying randomised-effect model evaluated. The analysis found no statistically significant differences between the CLIL and EFL groups in listening and reading performance. Concerning vocabulary the statistically significant difference in favour of CLIL (p<0,0001) with overall estimate effect 0,84 and confidence interval ranging from 0,56 to 1,11 was observed.
