From Frailty to Chronic Pain: Nutritional Status and Pain Trajectories After Hip Fracture in the Elderly.
Article in Orthopedic reviews, 2026. 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
Background: Hip fracture in elderly patients represents a major clinical challenge, with recovery influenced not only by surgical factors but also by frailty, nutritional vulnerability, inflammation and postoperative pain trajectories. While acute postoperative pain is well studied, determinants of pain persistence and chronification remain unclear. Objective: To investigate associations between nutritional screening tools, selected inflammatory and metabolic biomarkers, and postoperative pain outcomes in elderly patients undergoing hip fracture surgery. Secondary objectives included examining relationships with frailty and postoperative functional independence. Methods: Eighty patients aged ≥80 years undergoing surgical repair of femoral neck or intertrochanteric fractures were prospectively enrolled. Preoperative assessments included frailty evaluation, Mini Nutritional Assessment-Short Form (MNA-SF), modified Nutrition Risk in the Critically Ill (mNUTRIC) score, APACHE and SOFA scores, and laboratory biomarkers (albumin, CRP, RDW, LDH, ferritin and calcium). Pain intensity was assessed using the Visual Analog Scale preoperatively, acutely postoperatively, at 30 days and at six months. Functional independence was evaluated after discharge. Associations were analyzed using Spearman's rank correlation. Results: Acute postoperative pain was weakly associated with preoperative pain. Pain at 30 days and six months showed stronger associations with frailty, hypoalbuminemia, inflammatory markers and higher APACHE/SOFA scores. Lower MNA-SF and higher mNUTRIC scores were moderately associated with 30-day pain and strongly associated with chronic pain. Better nutritional status correlated with greater postoperative functional independence. Conclusion: Chronic postsurgical pain in elderly hip fracture patients reflects frailty, nutritional depletion and metabolic stress rather than surgical injury alone. Integrating nutritional screening into perioperative care may improve recovery.
