Immediate Effect of Modifying Lumbopelvic Motion During Sitting Knee Extension in People With Low Back Pain: A Repeated-Measures Study.
Article in Journal of chiropractic medicine, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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 aim of this study was to investigate the ability of people with low back pain (LBP) to modify the pattern of lumbopelvic rotation (LPR) when actively moving their lower limbs in sitting. Methods: In this repeated-measures study in 38 men with chronic mechanical LBP (mean age, 38.4 ± 10.6 years), the timing and magnitude of LPR were investigated before and during the contraction of abdominal muscles during active knee extension while sitting. The kinematic data were collected using a motion-capture system, and OpenSim software was used for data analysis. The time difference between the start of knee extension and the start of LPR was measured and then adjusted to the movement time of the knee. The maximum LPR angle was also measured. Results: Participants increased the time difference between the start of knee extension and the start of LPR when contracting the abdominal muscles ( Conclusion: People with LBP are able to modify early lumbopelvic motion during active lower limb movement while sitting. This may reduce the frequency of lumbopelvic motion during activities of daily living in sitting in these people.
