Is Age a Risk Factor for Early Postoperative Cage Subsidence After Transforaminal Lumbar Interbody Fusion? A Retrospective Study in 170 Patients.
Article in Global spine journal, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers, 1 of them a synthesis that pooled it.
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
STUDY
designRetrospective observational study.
objectivesWe aim to evaluate whether age is a risk factor for cage subsidence, and whether other patient characteristics, preoperative radiological or imaging parameters are associated with cage subsidence and the need for revision surgery in patients undergoing transforaminal lumbar interbody fusion (TLIF).
methodsPatient demographics and surgery-related information were extracted. Cage subsidence was evaluated using upright standing sagittal plane X-rays and defined as more than 2 mm migration of the cage into the adjacent vertebral body. Patients who received revision surgery within 1 year for any reason were recorded. Radiographic parameters were measured. Univariable logistic regression models were used to evaluate the risk factors for cage subsidence and need for revision surgery.
resultsAt 3-month and 1-year follow-up, cage subsidence was observed in 28 patients (16.5%) and 58 patients (34.1%), respectively. Twenty-seven patients received revision surgery within the first year after TLIF. Age (odds ratio (OR): 1.07 per year) and male sex (OR: 2.76) had a significantly increased odds ratio for cage subsidence 3 months after TLIF. Male sex (OR: 2.55) but not age was a significant risk factor for cage subsidence 1 year after TLIF. Of all assessed risk factors, only BMI (OR: 1.11 per kg/m
conclusionsAge was associated with cage subsidence 3 months but not 1 year after TLIF suggesting that age is only a risk factor for early cage subsidence and not in a longer follow-up.
