Validity of a diagnostic scale for acupuncture: application of the item response theory to the five viscera score.
Article in Evidence-based complementary and alternative medicine : eCAM, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
In acupuncture therapy, diagnosis, acupoints, and stimulation for patients with the same illness are often inconsistent among between Traditional Chinese Medicine (TCM) practitioners. This is in part due to the paucity of evidence-based diagnostic methods in TCM. To solve this problem, establishment of validated diagnostic tool is inevitable. We first applied the Item Response Theory (IRT) model to the Five Viscera Score (FVS) to test its validity by evaluating the ability of the questionnaire items to identify an individual's latent traits. Next, the health-related QOL scale (SF-36), a suitable instrument for evaluating acupuncture therapy, was administered to evaluate whether the FVS can be used to make a health-related diagnosis. All 20 items of the FVS had adequate item discrimination, and 13 items had high item discrimination power. Measurement accuracy was suited for application in a range of individuals, from healthy to symptomatic. When the FVS and SF-36 were administered to other subjects, a part of which overlap with the first subjects, we found an association between the two scales, and the same findings were obtained when symptomatic and asymptomatic subjects were compared regardless of age and sex. In conclusion, the FVS may be effective in clinical diagnosis.
