| Participants |
Type of Leishmania: L donovani Inclusion criteria: participants with CL who attended to Anuradhapura Teaching Hospital, Anuradhapura, Sri Lanka from April 2006 to June 2007 Exclusion criteria: not described N randomised: a total of 154 participants with 229 lesions were included in the study. IL 7% HSCS: 67; ILSSG: 87 Withdrawals: (4.5%: 7/154). HSCS: 3, ILSSG: 4 N assessed: 147 (95.45%) CL participants with 222 lesions completed treatments. HSCS: 64 (95.52%); ILSSG: 83 (95.40%). Age: mean 32 years (range 16 months to 74 years) Sex (male/female): 99/55, M:F ratio of 1.8:1 Baseline data:

| Interventions |
Type of interventions:
Duration of intervention: HSCS: 1‐29 weeks, depending on the size and the duration of the lesions (mean 8.78 weeks). SSG: 1‐13 weeks, depending on the size and the duration of the lesions (mean 5.11 weeks) Participants were seen weekly for the first 3 injections; fortnightly for the fourth and fifth injections; then monthly until cure. |
|
| Outcomes |
Clinical cure: the percentage of lesions that were cured with SSG and HSCS Number of injections required per each lesion in total for cure (scales: 1‐10 injections) Adverse effects: systemic side effects with SSG or HSCS. Local side effects: pain during injection. Scarring after healing, postinflammatory hyperpigmentation Time points reported: at the end of treatment. Participants were followed‐up every 3 months after cure for 18 months to assess recurrences and evidence of visceralisation |

| Risk of bias | ||
| Bias | Authors' judgement | Support for judgement |
| Random sequence generation (selection bias) | Unclear risk | Comment: insufficient detail was reported about the method used to generate the allocation sequence. |
| Allocation concealment (selection bias) | Unclear risk | Not reported |
| Blinding of participants and personnel (performance bias) All outcomes | Unclear risk | Quote: "double blind" Insufficient information to permit judgment |
| Blinding of outcome assessment (detection bias) All outcomes | Low risk | Quote: "double blind", "At each visit the patients were examined by the primary investigator who was blind to the therapy" Insufficient information to permit judgment |
| Incomplete outcome data (attrition bias) All outcomes | Low risk | 4.5% (7/154) did not complete the study |
| Selective reporting (reporting bias) | Unclear risk | No protocol was available; not registered. Insufficient information to permit judgment SD not provided for duration of treatment and number of injections |
| Other bias | Unclear risk | There was not enough information in the publication to assess if there were other biases present. |
