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
Prospective motion corrections in brain imaging for MRI are fairly challenging. Monitoring involuntary head movement inside MR scanner is crucial for prospective motion correction. This initial study delves into utilizing simulations to track the head's movements within an MRI scanner, achieved by measuring induced voltage changes from time-varying magnetic field gradients in head-mounted coils. The ultimate aim is to create an inventive approach for prospective motion corrections. The voltage induced in a circular coil of wire that is exposed to time-varying x-, y- and z-magnetic field gradients, is calculated for varying positions and orientations (POSE) of the coils. Similar steps are taken for a system of five coils confined to faces of a cube and it is established whether the voltage changes due to gradient pulses applied along three directions can be used to calculate the change in POSE of the set of coils. This induced voltage led to form a system of linear equations and then find a calibration matrix. Inverting the calibration matrix enables the estimation of movement parameters from the calculated voltage in the coils. Our software gives robust measurement of the six degrees of freedoms to monitor head movement accurately so far ≈0.3 mm and
