Outcomes
Primary outcome [1] 321366 0
Data-linkage to medical records and direct clinical assessment by doctors at outpatient clinic for complications.

Complications include rapid increase in size (>150% per month increase in volume), development of ulceration, or impairment of vital functions of infantile haemangioma. The lesions are measured using a ruler for its size. The other parameters can be seen directly with the naked eye.
Timepoint [1] 321366 0
At baseline, 1 month, 3 months, 6 months and 12 months (primary endpoint) after randomisation
Primary outcome [2] 321367 0
Data-linkage to medical records and direct clinical assessment by doctors at outpatient clinic for any further treatment required.

Further treatment include oral propranolol, laser therapy, corticosteroid injection or surgical excision. Decision is based on development of complications which in turn aligns to HK, US and UK protocols.
Timepoint [2] 321367 0
At baseline, 1 month, 3 months, 6 months and 12 months (primary endpoint) after randomisation
Secondary outcome [1] 374778 0
Data-linkage to medical records and direct clinical assessment by doctors at outpatient clinic for any reported side effects of topical timolol maleate by the carers of the child.
Timepoint [1] 374778 0
At baseline, 1 month, 3 months, 6 months and 12 months after randomisation.
Secondary outcome [2] 374779 0
Size in terms of length, width and thickness of haemangioma measured with paper measuring ruler and documented with photo
Timepoint [2] 374779 0
At baseline, 1 month, 3 months, 6 months and 12 months after randomisation.

Statistical methods / analysis
We hypothesised that TTM is superior to watchful waiting for treatment of haemangiomas. Assuming that the percentage of uncomplicated IH without need for further intervention would be 62% 13, whilst that after the use of TTM would be 99% 16, and the superiority margin 0.05, the required sample size with equal (1:1) allocation to achieve an 80% power (= 0.2) and a = 0.05 is 60 subjects (30 subjects in each group). Assuming a 5% dropout rate, we planned to recruit a total of 64 subjects into this study, with 32 subjects in the TTM group and 32 subjects in the no-TTM group. The primary and secondary analyses of all outcomes followed the intention-to-treat principle.

Patient characteristics were presented as frequencies and percentages for categorical data and means (SD) or medians (IQR) for continuous data.

Statistical analysis was performed using the Statistical Package SPSS 23 software. Categorical data was compared using the chi-square test or the Fisher Exact test (for cells less than 5), and odds ratio (OR) with 95% confidence interval (C.I.) was calculated. Continuous variables were compared using the independent t test or Mann-Whitney U test. For the secondary outcome, percentage changes over time at 3 months, 6 months and 12 months after study uptake were compared. Flat IH and subjects who defaulted the 12-month follow-up session were excluded from the secondary outcome analysis, while missing data were kept the same as the last measured size. IH were excluded from the secondary outcome analysis upon receiving additional treatment. A two-sided p-value of = 0.05 was considered significant.

Summary
Brief summary
Objective: To define the role of topical timolol maleate (TTM) in the treatment of infantile haemangiomata (IH). We hypothesised that TTM is superior to watchful waiting for treatment of IH.
Study design: In this single-centre randomised controlled trial, we included all <1-year-old infants within a 13-month period presenting with small (<2cm) superficial IH located at high risk areas (i.e. tip of ears, tip of nose, eyelids, acral areas, facial areas, scalp, neck, buttocks, perineum and axilla). Patients either received 12 months of 0.5% timolol maleate solution (study group) or watchful waiting (control group). Both groups were monitored and treated similarly. The primary outcome was IH with development of complications that required additional interventions. The secondary outcomes included side effects of TTM and change in IH size.
