Changes in Bone Metabolism After Sleeve Gastrectomy Versus Gastric Bypass: a Meta-Analysis.

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
backgroundGastric bypass (GB) and sleeve gastrectomy (SG) are two common types of bariatric surgery that carry many potential complications. Among these complications, bone metabolism-related diseases have attracted substantial attention; however, no meta-analysis of them has been performed to date.
methodsWe searched PubMed, Web of Science, The Cochrane Library, and Embase to identify relevant studies published before January 2019. The following indicators were evaluated: serum parathyroid hormone (PTH), calcium, phosphorus and 25-hydroxyvitamin D levels, body mass index (BMI), and bone mineral density (BMD).
resultsThirteen studies met our inclusion criteria. Overall results showed that patients undergoing GB had lower levels of 25-hydroxyvitamin D (MD = - 1.85, 95% CI (- 3.32, - 0.39) P = 0.01) and calcium (MD = - 0.15, 95% CI (- 0.24, - 0.07) P = 0.0006) as well as higher levels of PTH (MD = 3.58, 95% CI (0.61, 7.09) P = 0.02) and phosphorus (MD = 0.22, 95% CI (0.10, 0.35) P = 0.0005). The results of BMI and BMD were comparable in each group.
conclusionOur meta-analysis suggested that obese patients undergoing GB had lower levels of serum calcium and 25-hydroxyvitamin D as well as higher levels of serum phosphorus and PTH. To prevent postoperative bone metabolism-related diseases, appropriate postoperative interventions should be undertaken for particular surgical procedures.
