  1. DS = Dataset number; RR = Relative risk; MD = Mean difference; CI = Confidence interval; Not estimable = data from both treatment groups are essentially the same: p = 1.00.
  2. * Statistically significant difference, in favour of GIC
  3. ** Statistically significant difference, in favour of Resin
  4. 1 Different datasets reported from same trial
