Methods |
Study design: randomised controlled trial Setting/location: Afzalipour Hospital, Kerman University of Medical Sciences, Iran Study period: 1 year (2011‐12) Sample size calculation: a sample size of 40 participants per treatment group was planned, a probability of a type I error at alpha = 0.05 and beta = 0.1 to determine a 20% difference between topical terbinafine compared with control group |

Participants |
Type of Leishmania: L tropica Inclusion criteria: participants between 2‐60 years and without serious medical illness were included, not have received any other leishmanicidal treatment during last 3 months, duration of their lesions should be less than 6 months Exclusion criteria: cardiac, hepatic, renal and other systemic diseases; pregnant and nursing women; hypersensitivity to trial drugs N randomised: 80, 40 in each group Withdrawals: 0 N assessed: 80, 40 in each group Mean (SD) age: terbinafine: 16.3 years (14.8), IMMA: 20.74 years (19.4) Sex (n, %): terbinafine: male 18 (45); female 18 (45); the sex of 4 (10) participants was unknown. IMMA: male: 16 (40); female: 18 (45); the sex of 6 (15) participants was unknown Baseline data:

Interventions |
Type of interventions:
Co‐interventions: Both groups received cryotherapy every 2 weeks for 4 weeks Duration of intervention: group 1: 4 weeks, group 2: 3 weeks Duration of follow up: patients were followed monthly for 3 months after the treatment. |
|
Outcomes |
Clinical cure: clinical response was determined based on the following criteria:
Time to clinical cure: development of oartial and complete response to treatment in IMMA and terbinafine groups. Time points reported: the improving rate determined by measuring indurations at baseline, in the middle (day 10 for IMMA group and day14th for terbinafine group), and at the end of the study (day 21 for IMMA group and day 28 for terbinafine group) |

Risk of bias | ||
Bias | Authors' judgement | Support for judgement |
Random sequence generation (selection bias) | Low risk | The randomisation sequence was obtained by the use of a randomisation table. |
Allocation concealment (selection bias) | Low risk | A simple block randomisation list with a block size of 4 was accumulated by a team member who was not involved in the enlistment and follow‐up of the participants. The randomisation allocation concealment was carried out by sending the randomisation numbers in envelopes to a dermatologist who was responsible for giving the assigned treatment after each participant was en‐rolled. |
Blinding of participants and personnel (performance bias) All outcomes | High risk | Different administration of treatments: oral terbinafine and IMMA. |
Blinding of outcome assessment (detection bias) All outcomes | Low risk | This study was an assessor blind trial in which the outcome assessor was unaware of the drugs used by the participants. |
Incomplete outcome data (attrition bias) All outcomes | Unclear risk | Not described |
Selective reporting (reporting bias) | High risk | The study published does not report 2 primary outcomes: adverse effects and recurrence |
Other bias | Low risk | Other items assessed correctly reported |
