The effect of postnatal breastfeeding education/support offered at home 3 days after delivery on breastfeeding duration and knowledge: a randomized trial

For the Aksu 2011 trial, incomplete outcome data was at high risk of bias because it was not an intention-to-treat analysis and there was loss to follow-up (intervention group: 3+3/33, control group: 3+3/33; 54/66 followed up at 18 months, 82%).

“Not ITT analysis. There was some loss to follow-up (Intervention group: 3+3 /33, Control group: 3+3 /33). 54/66 were followed up at 18 months (82%).”

For the Aksu 2011 trial, other bias was at low risk because groups appeared comparable at baseline and no other bias was apparent.

“Groups appeared comparable at baseline. No other bias apparent.”

For the Aksu 2011 trial, random sequence generation was at low risk of bias because computer-generated random numbers were used.

“Use of computer-generated random numbers.”

For the Aksu 2011 trial, blinding of participants and personnel was at high risk of bias because blinding was not feasible, though outcome assessors could have been blinded.

“Not feasible, but the authors state,”

For the Aksu 2011 trial, selective reporting was at high risk of bias because the primary outcome was not pre-defined in the methods.

“The primary outcome was not pre-defined in the methods.”

For the Aksu 2011 trial, allocation concealment was at unclear risk of bias because the method used at the point of randomisation was not described.

“After the baseline interview, participants were randomly allocated to 1 of the 2 groups; the method used at the point of randomisation was not described.”

For the Aksu 2011 trial, blinding of outcome assessment was at high risk of bias because the intervention could not be blinded, though outcome assessors could have been blinded.
