  1. The table shows the statistically significant prognostic factors reported in at least two studies. The quality of the studies was ranked high if ≥60 points (≥80% of the maximum score), moderate if 45–59 points (≥60% and <80% of the maximum score) and low if <45 points (<60% of maximum score) were given. Using the QUIPS tool
