Protein intake, malnutrition, and its association with bone health after a hip fracture: A 3-month prospective study.

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: In this study, we describe the change in protein intake, nutritional status, bone markers, and bone mineral density (BMD) in older patients recovering from a hip fracture, from post-surgery till 3 months. Additionally, we explore the association between protein intake with bone markers, quantitative ultrasound (QUS) and BMD, and nutritional status with QUS and BMD. Methods: A 3-month prospective study in 96 adults aged ≥70 years with an acute hip fracture was conducted. Assessments after surgery and 3 months included protein intake (questionnaire), nutritional status [Mini Nutritional Assessment Short Form (MNA-SF)], procollagen type I N-terminal propeptide (PINP), C-terminal telopeptide of type I collagen (CTX), insulin-like growth factor 1 (IGF-1), parathyroid hormone (PTH) levels, QUS parameters, and BMD (dual-energy X-ray absorptiometry). Associations were assessed by adjusted linear mixed models. Results: At baseline, half of the patients (mean age 84 years, 63% females) had a low protein intake (<0.8 g/kg/d), which did not change over time. The patients had significant weight loss (median 3.6 kg) and the prevalence of (being at risk of) malnutrition increased from 20% to 64%. The PINP and IGF-1 levels increased over time, the CTX level remained stable, and the PTH level decreased. The protein intake was only associated with a QUS parameter in females (estimate 0.123, 95% Conclusions: A good nutritional status is associated with higher BMD in older hip fracture patients. The role of protein for bone health in these patients remains unclear. After a hip fracture, there is an increase in PINP.
