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
objectiveIn comparing the repeatability of the internal diameter and hemodynamic parameters of the dorsalis pedis artery measured by immersion ultrasound and contact ultrasound, the factors affecting the accuracy and repeatability of measurement were analyzed. This study aimed to provide a better method for ultrasound evaluation of the dorsalis pedis artery before flap transplantation.
methodsTwo senior sonographers measured the diameter of the dorsalis pedis artery (D) of 56 healthy volunteers, measuring at the same location and at different time points using water immersion and contact ultrasound. Color Doppler ultrasound was used to measure the hemodynamics of the dorsalis pedis artery, including peak systolic velocity (PSV), end diastolic velocity (EDV), and resistance index (RI). The interclass correlation coefficient (ICC) was used to evaluate the intraobserver and interobserver repeatability for each group's measurements.
resultsThe intraobserver and interobserver reproducibility of D, PSV, EDV, and RI measurements by water immersion ultrasound was very good. The intraobserver and interobserver reproducibility of the contact ultrasound measurements of D, PSV, EDV, and RI was good.
conclusionThe repeatability of water immersion ultrasound is better than that of contact ultrasound in the measurement of the dorsalis pedis artery. Water immersion ultrasound can improve the near-field resolution of superficial tissues and increase the display of the lengths of blood vessels in images, thereby suggesting its superiority in ultrasound examination of dorsalis pedis arteries.
