Study	Reason for exclusion
Anon 2010	Ongoing randomised controlled trial comparing treatment of leg telangiectasias with sclerotherapy versus laser with Nd:YAG 1064nm.
Blaise 2010	A randomised trial comparing ultrasound‐guided sclerotherapy with 1% versus 3% polidocanol foam in patients with incompetence of the great saphenous vein in CEAP clinical classes C2 to 5. Telangiectasias were not included.
Hamel‐Desnos 2010	Randomised, open, prospective study. After undergoing foam sclerotherapy for symptomatic varicose veins of the great or small saphenous, patients were randomised either to wear compression stockings for 3 weeks or to no compression stockings.
Isiklar 2003	Split‐body non‐randomised controlled trial comparing hypercompression versus no hypercompression following microsclerotherapy for venules and telangiectasias.
Kern 2004	Single‐blind, randomised study that compared chromated glycerin, polidocanol solution, and polidocanol foam used in sclerotherapy treatment of telangiectatic leg veins. Reticular veins of 1 mm to 3 mm were included as well as telangiectasias of 0.2 mm to 1 mm. Outcome data for telangiectasias was not presented separately.
Kern 2007	A randomised controlled trial comparing sclerotherapy for telangiectasias and reticular leg veins with compression for 3 weeks afterwards versus no compression afterwards.
Lupton 2002	Split‐body randomised comparison trial of sclerotherapy of telangiectasias with STS versus long‐pulsed 1064 nm Nd:YAG laser irradiation.
Neto 2001	Split‐body randomised controlled trial comparing hirudoid post‐sclerotherapy of microvarices and telangiectasias of the lower limbs to placebo post‐sclerotherapy.
Nootheti 2009	Split‐body, randomised, single‐blind trial comparing an additional 3 weeks of class I compression stockings to no additional stockings in patients whose reticular and telangiectatic leg veins were treated with sclerotherapy followed by one week of class II compression stockings.
Raymond‐Martimbeau 1995	This was a non‐randomised prospective, double‐blind study investigating the incidence, classification, and relationship with the deep venous system of telangiectasias in 525 consecutive patients treated with sclerotherapy.
Reis 1991	Placebo‐controlled trial assessing pain during sclerotherapy for telangiectasias that compares use of a topical anaesthetic cream to a neutral cream.
Sadick 1991	Non‐randomised, double‐blind paired‐comparison study to investigate the effects of increasing concentrations of hypertonic saline with regard to vessel diameter of varicose and telangiectatic leg veins. A second phase involved the non‐randomised addition of heparin to the sclerosant solution.
Schul 2009	Randomised trial comparing compression therapy to sclerotherapy for isolated refluxing reticular veins and telangiectasias.
Uncu 2010	Patients with telangiectasias and larger varicose veins up to 4mm were treated with compression sclerotherapy using polidocanol in foam or liquid form. Outcome data for telangiectasias (vessels <1mm) was not presented separately.
Weiss 1990a	Non‐randomised study investigating the incidence of side effects in patients whose telangiectasias were treated with compression sclerotherapy using hypertonic saline (HS), polidocanol (POL) 1%, both HS and POL 1%, or both POL 1% and POL 0.5%.
Weiss 1999	Comparison trial of compression stockings worn for 3 days, 1 week, or 3 weeks versus no compression following sclerotherapy for telangiectases, venulectases and reticular veins of the lower limbs.
