Altered ultrasonographic activity of abdominal muscles during breathing in males with and without nonspecific chronic low back pain.
Article in Journal of ultrasound, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
purposeThis study aimed to investigate the altered ultrasonographic activity of abdominal muscles during breathing in males with and without nonspecific chronic low back pain (NSCLBP).
designCross-sectional study.
methodsTwenty males with NSCLBP and 20 males without NSCLBP were recruited. Muscle thickness change was measured by ultrasonography during breathing in the end-inspiration and end-expiration phases for the transverse abdominis (TrA), internal oblique (IO), external oblique (EO), and rectus abdominis (RA) muscles. The data were normalized to the end-inspiration thickness. An independent t test was run to analyze the data at a confidence level of 95% (p < 0.05).
resultsThe participants with NSCLBP had thicker IO muscles in the end-inspiration (p = 0.030) and end-expiration (p = 0.017) phases as well as greater RA (p = 0.006) and smaller EO (p = 0.003) normalized thickness changes during breathing.
conclusionThe normalized thickness changes during breathing differed between the participants with and without NSCLBP. Reduced EO and increased RA activity may predispose the spine to further injuries. Therefore, normalizing the breathing pattern should be considered in the management of people with NSCLBP.
