The impact of preoperative handgrip strength on postoperative outcomes following transforaminal lumbar interbody fusion.
Observational study in Journal of orthopaedic surgery and research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
backgroundWith an aging population, the prevalence of lumbar spinal diseases necessitating surgical intervention is increasing. Handgrip strength (HGS) has emerged as a simple measure of muscle function that may correlate with surgical outcomes. However, the role of HGS concerning postoperative recovery following transforaminal lumbar interbody fusion (TLIF) is not well-studied, highlighting a gap in the literature regarding its potential as a prognostic tool.
methodsThis prospective observational study included 89 patients who underwent TLIF performed by a single surgeon. Patients were categorized into normal and low HGS groups based on preoperative HGS measurements. Demographics, baseline HGS, and surgical details were recorded, and outcomes were assessed using the JOA, EQ-5D-3L, and Barthel Index at 3, 6, and 12 months postoperatively. Generalized Estimating Equations were used to examine associations between baseline parameters and outcomes over time.
resultsAll patients were followed for at least one year, except for 15 (15.6%) who were lost to follow-up before the one-year mark. Patients with lower preoperative HGS were associated with significantly poorer postoperative functional outcomes. Specifically, a one-unit decrease in HGS was associated with a 2.551-point decrease in the JOA score (p = 0.008), a 0.142-point decrease in the EQ-5D-3L score (p = 0.007), and a 5.784-point decrease in the Barthel Index (p = 0.036). Additionally, male sex, higher body mass index, and lower Charlson comorbidity index were associated with better postoperative outcomes.
conclusionsLow preoperative handgrip strength is associated with poorer functional, quality of life, and independence outcomes up to 12 months after TLIF surgery. Assessing HGS preoperatively may provide clinicians with valuable information for identifying patients at risk of suboptimal recovery. Future research could explore intervention strategies to improve preoperative muscle function and potentially enhance recovery outcomes for patients undergoing TLIF.
