1 · What the graph read from it

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.

2 · The registry

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

Accurate prediction of human motor actions is essential for developing intuitive, responsive, and adaptive human-machine interaction systems. This study investigates the use of force myography (FMG) to predict knob-turning activity with varying torque values and arm angles. Participants performed knob-turning activities on three spiral springs with different torque values and at four arm angles. A convolution neural network, long short-term memory hybrid classification approach was employed to classify the FMG data and predict torque and arm angle with an overall accuracy of 95.87 ± 2.59% and 94.06 ± 2.44%, respectively. The study also shows that the presence of subcutaneous fat did not significantly affect the classification of torque and arm angle ([Formula: see text], Mann-Whitney U test). These findings demonstrate the potential of FMG as an effective method for accurately predicting activities of daily life involving tasks with varying torque and arm angles.
