The Effects of Vitamin D Supplementation on Pulmonary Function of Chronic Obstructive Pulmonary Disease Patients, before and after Clinical Trial.
Article in Diseases (Basel, Switzerland), 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
Vitamin D has several extra calcemic effects. Vitamin D deficiency is highly prevalent in chronic obstructive pulmonary disease (COPD) patients but little is known about it's association with lung function.
objectiveTo investigate whether supplementation with vitamin D could improve pulmonary function in COPD patients.
designBefore and after, double center, clinical trial.
settingHazrat Rasoul University Hospital, Tehran, and Imam Khomaini University Hospital, Ahvaz, Iran.
participants24 patients with mild to very severe COPD.
interventionLoading dose of 300,000-600,000 International Units (IU) of vitamin D, then 50000 IU weekly for 12 weeks. MEASUREMENTS: The outcomes included forced expiratory volume in one second (FEV1), forced vital capacity (FVC), vital capacity (VC), forced expiratory flow between 25%-75% of forced vital capacity (FEF 25%-75%), exercise capacity according to the six minute walk test(6MWT) and the saturation of oxygen during exercise.
resultsThe mean FEV1 (
conclusionPulmonary function and exercise capacity did not improve with vitamin D supplementation in COPD patients.
