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
Objectives: This study aims to develop a sulcus vocalis model in the excised canine larynx and to investigate the validity of the model. Methods: Type II sulcus vocalis was created by continuous intradermal suture in six excised canine larynges. We investigated the validity of the model based on phonatory (aerodynamic and acoustic) measures, laryngeal videostroboscopy (LVS), and histological examination. The aeroacoustic parameters included phonation threshold pressure (PTP), fundamental frequency ( Results: In all the experimental specimens, there were significant increases in the PTP ([6.61 ± 1.66] cm H Conclusions: Type Ⅱ sulcus vocalis was successfully created in excised canine larynx. The aeroacoustic and LVS analysis of this model resembled the characteristics of patients with sulcus vocalis. The model could be helpful to elucidate the pathology of the phonation, and evaluate and compare the treatments for sulcus vocalis.
