Validation of the Olfato-UP olfactory test for the Brazilian population.
Article in Brazilian journal of otorhinolaryngology. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectiveTo validate the Olfato-Up test in adults and elderly individuals from the Brazilian population.
methodsThe study was conducted in three stages. The first phase evaluated the population's familiarity with the chosen scents. The second phase assessed the performance of the Olfato-Up test, including sensitivity, specificity, accuracy, and cut-off determination. The third phase evaluated the test's reproducibility and the time required for its application.
resultsAll fragrances met the minimum accuracy requirements for the normosmic population. The cut-off score for anosmia and severe hyposmia was 7, with a sensitivity of 88.2%, specificity of 86.6%, accuracy of 86.7%, and an Area Under the Curve (AUC) of 90.7% for anosmia. For severe hyposmia, the sensitivity was 70.2%, specificity was 96%, accuracy was 89.8%, and the AUC was 90.1%. The Intraclass Correlation Coefficient (ICC) was 0.89. The Pearson correlation test revealed a correlation coefficient ofr = 0.811 (p = 0.001) and Bland-Altman test indicated a mean difference of -0.18 (95% CI -1.68 to 1.32). The average application time was 3.8 min (SD = 0.79).
conclusionOlfato-Up test demonstrated excellent reproducibility, a short application time, and high sensitivity, specificity, and accuracy for detecting anosmia and severe hyposmia. LEVEL OF EVIDENCE: 2:
