The Association of Vitamin D Status and Pre-operative Physical Activity in Patients with Hip or Knee Osteoarthritis.
Article in Journal of restorative medicine, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
backgroundVitamin D is important for musculoskeletal health and may have significant implications for maintaining physical activity in elderly patients. Our goal was to investigate whether serum 25-hydroxyvitamin D (25OHD) levels are associated with pre-operative physical activity in patients who are offered elective knee or hip joint replacement surgery.
methodsWe performed a single-center, retrospective analysis of patients who had elective knee or hip replacement surgery from 2002 to 2012. To investigate the association of serum 25OHD levels with pre-operative physical activity, as assessed by the University of California, Los Angeles (UCLA) activity scale, we performed a multivariable logistic regression analysis while controlling for age, sex, race, body mass index, American Society of Anesthesiologists physical status score, and season.
resultsWe identified 182 patients who met inclusion criteria. Mean (± standard deviation) 25OHD level and UCLA activity scale score were 29±13 ng/mL and 4±2, respectively. Patients with 25OHD levels <20 ng/mL were almost three times more likely to have UCLA activity scale scores ≤3 [adjusted odds ratio 2.78; 95% confidence interval 1.72-9.17]. Further adjusting for "type of 25OHD assay" or "type of joint surgery" did not materially change this result.
conclusionIn our cohort of knee or hip joint replacement surgery patients, 25OHD levels were associated with pre-operative physical activity scores. Prospective, randomized, clinical trials are needed to verify whether optimizing pre-operative vitamin D status may improve physical activity and influence clinical decision-making in knee or hip joint replacement surgery candidates.
