Vitamin D supplementation for the prevention of vitamin D deficiency after bariatric surgery: a systematic review and meta-analysis.
Synthesis in European journal of clinical nutrition, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 12 papers, 2 of them syntheses that pooled 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.
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
objectiveTo evaluate the efficacy of vitamin D supplementation on the prevention of postoperative vitamin D deficiency.
methodsPubMed, Embase, Web of Science, and Cochrane library were searched. Prospective studies evaluating the effects of vitamin D supplementation in patients who had undergone bariatric surgery were included. Meta-regression was performed to explore heterogeneity, and assess the relationship between dosage of vitamin D supplementation, study design, and prevalence of vitamin D depletion.
resultsTwelve studies enrolling 1285 patients met the inclusion criteria, and were included. Vitamin D supplementation was associated with significant improvements in 1-year Vitamin D depletion and 1-year 25-OHD level. A daily supplement of more than 800 IU vitamin D significantly reduced the prevalence of 1-year Vitamin D depletion, but the dosage of less than 800 IU did not. Significant decrease in prevalence of 1-year Vitamin D depletion was observed in randomized controlled trials (RCTs), but not in non-RCTs. For the 1-year 25-OHD level, significant elevation was found in the studies irrespective of the study design and dosage of vitamin D supplementation. Meta-regression showed that there was significant relationship between vitamin D depletion and study design, but not between vitamin D depletion and the dosage of vitamin D supplementation.
conclusionVitamin D supplementation with a daily dosage of more than 800 IU is effective in preventing postoperative vitamin D deficiency and improving the 25-OHD level. However, the results should be interpreted cautiously since there was significant heterogeneity among the studies.
