| Methods | Randomised blinded placebo controlled trial |
| Participants | Preterm infants born at < 33 weeks' PMA with a haemodynamically significant PDA (diameter > 1.5 mm with clinical symptoms). were treated with a 5‐day course of oral paracetamol or placebo |
| Interventions | Infants were treated with a 5‐day course of oral paracetamol (n = 27) or placebo (n = 28) |
| Outcomes | Primary outcome: ductal closure by 48 h after treatment completion and decrease in size > 25% was a secondary outcome |
| Notes | By early January 2018 the study has only been reported in abstract form, with insufficient information to allow us to include the study in our update of the review. |
