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
objectivesTo explore the relationship between the triglyceride-to-high-density lipoprotein cholesterol(TG/HDL-C) ratio and spinal deformity severity.
methodsThis retrospective study analyzed 159 preoperative spinal deformity patients from Guangzhou First People's Hospital (2019-2025). Spinal deformity severity was assessed using Cobb angle measurements. Serum TG and HDL-C levels were measured to calculate the TG/HDL-C ratio. Multivariable logistic regression evaluated the association between the TG/HDL-C ratio and deformity severity. Subsequent restricted cubic spline (RCS) analysis with four knots examined potential nonlinear relationships. Receiver operating characteristic (ROC) curve analysis assessed the ratio's predictive performance. Bootstrap validation with 1,000 resamples was used for internal validation. Comprehensive subgroup analyses with interaction tests evaluated the consistency and potential effect modification of observed associations. Three sensitivity analyses were performed to validate robustness.
resultsThe significant inverse association was observed between TG/HDL-C ratio and spinal deformity severity. Multivariable regression confirmed a stable negative correlation after adjustment (OR = 0.44). Quartile analysis showed the highest ratio quartile had significantly lower deformity severity than the lowest quartile. RCS revealed a linear dose-response relationship, while ROC demonstrated moderate predictive value (AUC = 0.720). Excellent calibration was achieved (mean absolute error = 0.037). Subgroup analyses indicated consistent associations across populations, though no interaction terms survived multiple comparison correction. Sensitivity analyses confirmed that the association remained consistent across alternative modeling strategies, reinforcing the stability of the main findings.
conclusionsLower TG/HDL-C ratio correlates with severe spinal deformities, possibly reflecting metabolic dysfunction, inflammation, or bone loss.
