Osteomalacia Prevalence, Biochemical Profile, and Histology in Patients with Low-Energy Hip Fractures Over the Age of 45.

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
Our objective was to determine the prevalence of osteomalacia in low-energy hip fracture patients over the age of 45, based on biochemical and histological measures. This cross-sectional study included 72 patients over 45 with low-energy mechanism hip fractures. Samples of fasting venous blood were taken for hemograms and serum biochemistry analyses. Bicortical biopsies of the iliac crest were obtained, processed, and evaluated by an expert pathologist for osteomalacia. Biochemical osteomalacia (b-OM) is defined according to a distinct criterion. A low level of serum calcium, phosphorus, albumin, and 25OHD was found in 43.1, 16.7, 73.6, and 59.7% of patients, respectively. 50.0% of patients had high serum alkaline phosphatase (ALP) levels. b-OM was found in 30 (41.7%), and no significant association was found with PTH, Cr, Alb, age, sex, fracture type, side of the trauma, and season were not associated with osteomalacia. Osteomalacia was diagnosed on histopathological analysis in 19/72 (26.7%), and 54/72 (75.0%) of all cases fulfilled b-OM criteria. In the histologic evaluation, osteoid seam width, osteoid surface, and osteoid volume were 28.5 µm, 25.6, and 12.1%, respectively. The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of the biochemical test for detecting osteomalacia were 73.6, 64.2, 42.4, 87.2, and 66.7%, respectively. Up to 30% of elderly patients with low-energy hip fractures are affected by osteomalacia. A biochemical screening along with a bone biopsy and histopathologic evaluation may be logical in a high-risk population for osteomalacia diagnosis.
