Measuring Lumbar Motion Angle With a Small Accelerometer: A Reliability Study.
Article in Journal of chiropractic medicine, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Objective: The purpose of this study was to investigate the reliability of measuring the lumbar motion angle using a small accelerometer for movement tests in the sagittal plane, and to determine the number of measurements required to obtain reliable data. Methods: In total, 102 healthy adults (56% women, 44% men; 20.1 ± 1.1 years of age) participated in this study. The intra- and interexaminer reliability of lumbar motion angle measurements during forward and backward trunk bending and prone hip extension were investigated. Lumbar motion angles were measured with small accelerometers placed at the thoracolumbar transition, lumbosacral transition, and thigh, during motion and at the final position. Intraclass correlation coefficients and Bland-Altman analysis were used for statistical analysis. Results: The intraclass correlation coefficients ranged from 0.6 to 0.8 in intraexaminer analyses and from 0.5 to 0.7 in interexaminer analyses. Intraexaminer systematic biases were found only in the maximum angle of trunk forward bending. Interexaminer biases were found in all angles of trunk forward bending. Conclusion: In the measurement of lumbar motion angle in the sagittal plane using a small accelerometer, it was necessary to repeat measurements 2 to 4 times, because a single measurement was not sufficiently reliable either within or between examiners.
