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
introductionThe present study aimed to validate the Voice-Related Quality of Life (V-RQOL), vocal self-assessment questionnaire for Spanish.
methodsThe validation and psychometric properties were developed according to the criteria of the Scientific Advisory Committee of Medical Outcomes Trust (SAC). The Spanish translation for linguistic and cultural adaptation of the V-RQOL was used. The study involved 193 participants, including 90 vocally healthy individuals and 103 patients with voice disorders, to establish validity. To evaluate reliability, the protocol was applied to 40 participants with dysphonia, who answered it twice before the treatment. Then to determine response changes, the responses of 13 dysphonic participants to the V-RQOL for Spanish were analyzed after intervention and then compared to the initial ones. Clinicians contrasted subjects' V-RQOL results with a perceptual analysis of voice quality using the GRBAS scale. In order to determine sensitivity and specificity cut-off values, tools results were subjected to the receiver operating characteristic curve analysis. The sensitivity was obtained from the experimental group (dysphonic group) and the specificity from the control group (non-dysphonic group).
resultsThis version of the V-RQOL questionnaire may be used as part of the standard assessment process of people with voice complaints and as an outcome of treatment efficacy in clinical trials.
conclusionA validation of the V-RQOL for Spanish in Chilean population was achieved.
