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
Background: Depression is a prevalent mental health disorder that significantly impairs psychosocial functioning and quality of life. Recent advances in health sciences and digital technologies have highlighted the potential of voice acoustic parameters as objective indicators of health status, including depression. Methods: A bibliometric analysis, systematic literature review, and meta-analysis were conducted to consolidate and critically evaluate the current evidence regarding the relationship between voice acoustic parameters and depression. The search was performed in January 2024 across seven databases, including PubMed, Web of Science, and Scopus. Studies were included if they involved participants with clinically significant depression, identified either through formal diagnostic criteria or through validated depression rating scales with established clinical thresholds and explicitly reported voice acoustic parameters. A total of 31 potential publications were identified and analyzed, and after full-text reading, 17 publications were included. Only six out of the 17 included studies reported sufficient numerical fundamental frequency (fo) data for meta-analysis; other parameters could not be synthesized quantitatively due to a lack of extractable values. Results: The bibliometric analysis suggests an evolution from studies identifying "valid" assessment tools towards the modeling of potential discriminatory factors. The mean difference (MD) suggests a decreased fo of 1.82 Hz among participants identified with depression compared to participants identified as the control group. However, the difference between the groups was not statistically significant ( Conclusions: Voice acoustic parameters seem to have the potential to be noninvasive, cost-effective biomarkers for measuring and monitoring depression symptomatology. Although there was a trend of decreased fo of 1.82 Hz among participants identified with depression compared to participants identified as the control group, the meta-analysis suggests a nonsignificant difference in average values.
