Halitosis Relief Effect of Mouthwash Containing Lespedeza cuneata Extract: A Randomised, Double-Blind, Placebo-Controlled Study.
Trial report in Oral health & preventive dentistry, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
purposeTo evaluate the effect of a mouthwash containing Lespedeza cuneata extract (LCE) on halitosis as an alternative to chemical mouthwashes. The effect of this natural mouthwash on halitosis-causing bacteria (HCB) was clinically evaluated. MATERIALS AND
methodsA total of 84 subjects among 103 participants were recruited from the M Dental Clinic (Busan, South Korea) in this randomised, double-blind, placebo-controlled study. The participants were divided into two groups: 41 in the saline-gargle group (saline group) and 43 in the LCE-gargle group (LCE group). A week before the experiment, scaling and oral health education were conducted to standardise the subjects' oral condition. For clinical evaluation, halitosis and HCB were evaluated pre-gargle (baseline), immediately after gargling (treatment), and 5 days after gargling (5 days post-treatment). Statistical analysis was performed using SPSS for Windows.
resultsThe level of subjective improvement was statistically significantly greater in the LCE group than the saline group (p < 0.05). Compared with the saline group, the LCE group showed reduced halitosis after 5 days of application. Furthermore, halitosis statistically significantly decreased over time (p < 0.05). Moreover, the LCE group showed a statistically significant decrease in the number of all six HCBs (p < 0.05).
conclusionLCE gargle was effective in reducing halitosis both subjectively and objectively, suggesting an antibacterial effect on HCBs in the oral cavity. Thus, LCE, which can be used as a safe mouthwash ingredient, can promote oral health and will be valuable for the oral healthcare product industry. It might also be helpful for people suffering from halitosis.
