Effects of Viola odorata syrup on sleep quality in menopausal women: a randomized, triple-blind, controlled trial.
Trial report in Sleep & breathing = Schlaf & Atmung, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
purposeThe present study aimed to assess the effects of Viola odorata syrup on the sleep quality of postmenopausal women.
methodsThis triple-blinded randomized clinical trial was conducted on menopausal women presenting to the healthcare centers in Mashhad, Iran, in 2019. The participants were selected using simple random sampling. Participants received 5 ml syrup V. odorata or placebo twice a day for 1 month. Data were collected using the Pittsburgh Sleep Quality Index. The data were analyzed using SPSS version 25.
resultsThe 118 eligible women enrolled in the study were divided into two groups of V. odorata syrup and placebo (n = 59 each). The analysis was conducted on only 84 menopausal women (42 in each group) due to exclusions. Exclusions consisted of 12 participants who withdrew from the study due to unwillingness to cooperate, 8 who had irregular consumption of the therapeutic syrup, 6 with inaccurate completion of the questionnaire, and 8 due to lack of accessibility. The two study groups were homogenous in terms of demographic characteristics. Before the intervention, no significant difference was observed in the mean PSQI score between the two groups (9.2 ± 2.9 vs. 8.4 ± 2.5) (P = 0.18). However, a significant difference was seen in the mean PSQI score between the two groups (4.9 ± 1.9 vs. 8.1 ± 2.1, P < 0.001) after the intervention.
conclusionsThe findings of this study suggest that V. odorata syrup may be a useful therapeutic agent to improve the sleep quality of menopausal women. REGISTRATION CODE: IRCT20180514039660N1.
