The Hidden Angles: Predictive Indices of Degenerative Spondylolisthesis at L4-5.
Article in International journal of general medicine, 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
Objective: To examine the relationship between facet joint orientation, alignment, degeneration, and degenerative spondylolisthesis (DS) at lumbar vertebra L4-5. Methods: A retrospective study of 114 DS patients and 114 non-DS patients admitted to our hospital from May 2019 to April 2024. We compared facet joint angle (FJA), FJA difference, FJA asymmetry, L4 inclination angle (L4IA), Weishaupt classification, paraspinal muscle cross-sectional area (CSA), pedicle-facet angle (P-F angle), and P-F angle asymmetry between the two groups. We also analyzed FJA and slippage index changes across Weishaupt grades and their correlation using Pearson correlation. The predictive value of facet joint direction indices for DS at L4-5 was assessed using ROC curves. Results: The DS group showed reduced FJA and FJA difference, increased left asymmetry, higher L4IA levels, and a greater proportion of grade II and III in Weishaupt classification compared to the non-DS group (P<0.05). FJA decreased while the slippage index increased with more degeneration (P<0.05). Weishaupt classification was negatively correlated with FJA (r=-0.823, P<0.001), but positively with the slippage index (r=0.756, P<0.001). The P-F angle was significantly higher in the DS group (P<0.05). Cut-off values for FJA, L4IA, and P-F angle were 42.57, 9.63, and 122.17, with AUC values of 0.893, 0.766, and 0.858, respectively, indicating predictive value for DS at L4-5. Conclusion: The DS group had smaller FJA, larger L4IA and P-F angle, and more severe facet joint degeneration at L4-5, suggesting a strong link between DS at L4-5 and facet joint sagittalization, levelization, and degeneration.
