Possible efficacy of Lavender and Tea tree oils in the treatment of young women affected by mild idiopathic hirsutism.
Trial report in Journal of endocrinological investigation, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled it.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundHirsutism is defined as the presence of excessive terminal hair in androgen-dependent areas of a woman's body. Regarding this it has been suggested that Lavender and Tea tree oils may have antiandrogenic activities.
aimTo evaluate therapy based on Lavender and Tea tree oils in women suffering from mild idiopathic hirsutism (IH). SUBJECTS AND
methodsA prospective, open-label, placebo- controlled, randomized study was performed: women affected by mild IH were randomly assigned to receive oil spray containing Lavender and Tea tree oils (group T) (no. = 12) or placebo (group P) (no. = 12) twice a day for 3 months in areas affected by hirsutism. Evaluation of hirsutism was carried out at baseline and after 3 months by Ferriman-Gallwey score and by measuring hair diameter taken from some body areas. A hematological and hormonal evaluation was carried out at baseline and after 3 months.
resultsNo significant variations were found in any of the hormones studied in groups T and P between baseline and after 3 months. A statistically significant decrease of hirsutism total score and of hair diameter was found in group T, while no statistically significant difference in these two parameters was observed in group P; in group T percentual reduction of hair diameter was significantly greater than in group P.
conclusionsLavender and Tea tree oils applied locally on skin could be effective in reducing mild IH; this treatment could represent a safe, economic and practical instrument in the cure of this disease.
