1 · What the graph read from 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.

2 · The registry

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

backgroundVitamin D, calcium, and bone metabolism markers play a critical role in skeletal health; however, their relationship with different hip fracture types remains uncertain. This study aimed to investigate serum levels of 25(OH) vitamin D, calcium, parathyroid hormone (PTH), alkaline phosphatase (ALP), phosphorus, total protein, and albumin in elderly patients with femoral neck fractures (FNF) and intertrochanteric femur fractures (ITFF), compared to a control group.

methodsThis retrospective study included 375 patients aged 65 years and older, comprising 117 patients with ITFF, 97 with FNF, and 161 control cases (coxarthrosis/gonarthrosis). Serum biochemical parameters were analyzed using standard laboratory methods. Fractures were classified according to the AO/OTA (Arbeitsgemeinschaft für Osteosynthesefragen/Orthopaedic Trauma Association) system by two independent observers, and interobserver agreement was assessed using Cohen's kappa coefficient (κ=0.89). Group comparisons were performed using one-way analysis of variance (ANOVA) followed by post hoc Bonferroni tests. A p value <0.05 was considered statistically significant.

resultsVitamin D levels were significantly lower in both the ITFF and FNF groups compared to controls (p<0.01), while no significant difference was observed between the ITFF and FNF groups (p>0.05). Similarly, calcium, total protein, and albumin levels were lower in fracture groups than in controls (p<0.01). In contrast, PTH levels were significantly higher in patients with fractures (p=0.001).

conclusionDeficiencies in vitamin D and calcium were associated with an increased risk of hip fractures but did not appear to influence fracture pattern. These findings suggest that systemic biochemical parameters should be emphasized in comprehensive fracture risk assessment, underscoring the importance of preoperative evaluation and postoperative correction of metabolic deficiencies in patients with hip fractures.
