Relationships between psoas muscle index, lumbar lordosis, and chronic low back pain in middle-aged and elderly people.

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
purposeThe Psoas Muscle Index (PMI) has emerged as a rapid assessment method for evaluating psoas muscle quality. In recent years, chronic low back pain (CLBP) and lumbar lordosis (LL) have been significant areas of research interest. However, there is a notable gap in the literature, with no studies investigating the relationship between PMI and CLBP, nor any research examining the potential interconnections among PMI, LL, and CLBP. This study aimed to describe the cross-sectional relationships among these three factors.
methodsThis retrospective study analyzed data from 976 patients with low back pain and 120 healthy individuals aged 45 or older who reported no history of low back pain. Ultimately, the final analysis included 230 middle-aged and elderly subjects (aged 45 or older). The Subjects were divided into the CLBP group (duration > 1 year) and the control group(no low back pain at all). This study selected the PMI(cross-sectional area of psoas major muscle at L4/height
resultsThe PMI of men and women in the CLBP group (males:7.3 ± 1.6; females:5.9 ± 1.1) was significantly lower than that of the control group (males:8.0 ± 1.4; females:6.8 ± 1.1) (p < 0.05). The LLA was decreased in the CLBP group compared to the control group (males: 22.9°±7.6° vs. 37.0 ± 6.9; females: 22.7 ± 10.1 vs. 33.1 ± 7.0) (p < 0.001). Furthermore, no correlation between PMI and LLA was observed in both male (r = 0.091, p = 0.002) and female (r = 0.073, p < 0.003) subjects.
conclusionThere is a significant cross-sectional association among PMI, LL, and CLBP. This indicates a potential interaction between reduced PMI and altered LL, which may contribute to CLBP development.
