Methods	Single‐centre parallel RCT in Thailand.
Participants	65 participants (male 36; female 29) with a mean age of 36 years presenting within 24 hours with partial‐thickness burns < 15% TBSA. Exclusion criteria included full thickness burn; pregnancy; compromised immune system; hypersensitivity to alginate silver dressing
Interventions	Ionic silver dressing (Askina Calgitrol Ag) changed every 5 days until wound closure versus daily SSD changes
Outcomes	Time to wound healing Pain Number of dressing changes Nursing time
Notes
Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Unclear risk	"...were identified and randomised into two groups..." Inadequate information presented to determine whether sequence was unpredictable
Allocation concealment (selection bias)	Unclear risk	Inadequate information available to determine whether sequence was concealed from study personnel and participants
Blinding (performance bias and detection bias) All outcomes	High risk	Open‐label protocol; wound dressings changed at different times Not clear whether outcome assessors were blind to treatment group assignment
Incomplete outcome data (attrition bias) All outcomes	Low risk	No losses to follow‐up or withdrawals
Selective reporting (reporting bias)	Unclear risk	Cannot ascertain whether outcomes were measured but not reported
Other bias	Low risk	None detected
