Relationship of the lumbar Lordotic angle to the abdominal aortic deviation and abdominal aortic diameter.
Article in Scientific reports, 2025. 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
In anterior approaches during lumbar disc surgery, knowledge of abdominal aorta (AA) deviation and the lumbar lordotic angle (LLA) may provide surgeons with greater foresight in surgical planning and assist in preventing complications. This study aimed to determine the effect of AA deviation on AA morphometry and the effect of the LLA on both AA deviation and AA morphometry. A total of 499 individuals (259 females, 240 males) with a mean age of 50.60 ± 17.96 years were included in this retrospective study. On 2D computed tomography angiography (CTA) images, LLA and AA diameters were measured at 3 different vertebral levels. The vertebral levels of AA deviation were determined on 3D images. While the AA diameter values were greater in individuals with AA deviation (p < 0.001), it was observed that the level of deviation did not affect AA morphometry (p > 0.05). AA deviation was most frequently observed at the L2-L3 level in females, while the mid-L3 level was the most common site of AA deviation in males (p = 0.019). LLA was significantly greater in females compared to males (p = 0.015), but it was not affected by the presence of AA deviation (p = 0.373). The data from this study could provide guidance for endovascular interventions and anterior lumbosacral surgical procedures and could make a valuable contribution to the existing literature.
