Development of a Simple New Method to Detect Oral Malodor Using a Hydrogen Sulfide Detector Tube.

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
Aim: Many patients visit dental clinics complaining of oral malodor. However, there is no simple, inexpensive tool for assessing oral malodor. Therefore, this study developed a simple method using a detector tube. Materials and Methods: A detector tube was created to detect hydrogen sulfide based on the color change of an indicator (GASTEC, Kanagawa, Japan). We confirmed the ability to detect hydrogen sulfide concentrations of 200 ppb, which corresponds to the human olfactory threshold, using standard gas. The hydrogen sulfide detector tube was used to evaluate oral malodor in 42 outpatients aged 16-80 years, and the results were compared with an organoleptic test (OLT) and volatile sulfur compound (VSC) concentrations measured using a portable sulfide monitor. Results: Comparing the hydrogen sulfide detector tube with the OLT score, the sensitivity was 0.90 and the specificity was 0.74 for OLT score ≧2.75 ( Conclusion: The new hydrogen sulfide detector tube, when used in combination with OLT, should be useful for determining "clearly noticeable oral malodor".
