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 translate and validate Hebrew versions of two patient-reported outcome measure questionnaires: the Self-Reported Mini Olfactory Questionnaire (Self-MOQ) and the Brief Questionnaire of Olfactory Disorders (Brief-QOD).
methodsA forward-backward translation process was conducted for both questionnaires. All participants rated their sense of smell using a general Visual Analog Scale (VAS) ranging from 0 (no dysfunction) to 10 (severe dysfunction). The patient group completed the questionnaires and the SNOT-22 questionnaire once. A control group of healthy participants completed the questionnaires twice to evaluate test-retest reliability. Subsets of both groups took the Sniffin' Sticks test.
resultsThe translation process resulted in Hebrew versions deemed clear and culturally appropriate. A total of 91 individuals were enrolled in the control group and 62 in the patient group. The Hebrew versions of the Self-MOQ and Brief-QOD demonstrated high internal consistency (Cronbach's α of 0.79-0.94 in the full sample) and overall test-retest reliability. The patient group had higher scores than the control group across all measures (p < 0.001). Logistic regression indicated that the Self-MOQ was the strongest predictor of group membership, while the Brief-QOD QOL and Visual Analog Scale components also significantly contributed. Receiver operating characteristic curve analysis identified an optimal Self-MOQ cutoff score of ≥ 2 for distinguishing patients from controls, with excellent accuracy (AUC = 0.97).
conclusionsThe Hebrew Self-MOQ and Brief-QOD are reliable and valid tools for assessing olfactory dysfunction in the Hebrew-speaking population. Future research should evaluate questionnaire results after clinical interventions.
