Diagnostic reproducibility of thymic epithelial tumors using the World Health Organization classification: note for thoracic clinicians.
Article in General thoracic and cardiovascular surgery, 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
objectiveHistopathological diagnosis of thymic epithelial tumors according to the current World Health Organization classification is not adequately reproducible; however, most thoracic clinicians are unaware of this. We illustrate this problem in practical settings to raise clinician awareness.
methodsAn expert pathologist specialized in thymic pathology and a trained general pathologist independently diagnosed 158 resected thymic epithelial tumors. Assuming that the expert's diagnoses were more accurate, the two pathologists' diagnoses were judged to be concordant when tumor subtypes (thymoma) or categories (thymic carcinoma and neuroendocrine tumor) were in agreement.
resultsThe concordance rates for different thymoma subtypes were 75 % (3/4), 30 % (11/37), 100 % (17/17), 80 % (39/49), and 53 % (9/17) for types A, AB, B1, B2, and B3, respectively. Discordant cases of type AB thymoma were mainly diagnosed as type B1 or B2 by the general pathologist. Discordant cases of type B2 thymoma were diagnosed as type AB, B1, or B3, and discordant cases of type B3 thymoma were diagnosed as type A, B2, or carcinoma. Discordant cases of thymic carcinoma were diagnosed as type A or B3 thymoma.
conclusionInvestigation of the concordant and discordant cases suggested that reasonable discrepancies can occur because of the noncommittal categorical boundaries inherent in this classification. Thoracic clinicians should consider this potential problem in daily practice.
