Increased Early Postoperative Complication Rate after Osteoporotic Hip Fracture in Patients with Low 25 (OH) Vitamin D Levels.
Observational study in Nutrients, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
This study investigated the association of preoperative 25-hydroxy (25 (OH)) vitamin D levels with postoperative complications in osteoporotic hip fracture patients following surgery. We hypothesized that patients with low concentrations of 25 (OH) vitamin D might have an increased risk of developing adverse outcomes. Between January 2019 and December 2020, a retrospective observational study was conducted, including low-energy fragility fractures at the proximal femur. Regarding preoperative 25 (OH) vitamin D levels, patients were divided into two groups (<30 ng/mL and ≥30 ng/mL). Early and late postoperative complications were assessed and graded according to the Clavien-Dindo classification system. Logistic regression analysis was performed to demonstrate the association between preoperative 25 (OH) vitamin D levels (<30 ng/mL, ≥30 ng/mL) and postoperative complications after adjusting for age and sex. Of 314 patients, 222 patients (70.7%) had a 25 (OH) vitamin D level of <30 ng/mL. The mean serum 25 (OH) vitamin D level was 22.6 ng/mL (SD 13.2). In 116 patients (36.9%), postoperative complications were observed, with the most occurring in the short term (95 patients, 30.2%). Late postoperative complications were present in 21 patients (6.7%), most graded as Clavien I (57.1%). Logistic regression analysis identified a low vitamin D level (<30 ng/mL) as an independent risk factor for early postoperative complications (OR 2.06, 95% CI 1.14-3.73,
