1 · What the graph read from 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.

2 · The registry

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

backgroundThe prevalence of type 2 diabetes is growing in both developed and developing countries and is strongly linked with the prevalence of obesity. Bariatric surgical procedures such as laparoscopic vertical sleeve gastrectomy (LVSG) and laparoscopic Roux-en-Y gastric bypass (LRYGB) are increasingly being utilized to manage related comorbid chronic conditions, including type 2 diabetes.

methodsA systematic review of randomized controlled trials (RCTs) was undertaken using the PRISMA guidelines to investigate the postoperative impact on diabetes resolution following LVSG versus LRYGB.

resultsSeven RCTs involving a total of 732 patients (LVSG n = 365, LRYGB n = 367) met inclusion criteria. Significant diabetes resolution or improvement was reported with both procedures across all time points. Similarly, measures of glycemic control (HbA1C and fasting blood glucose levels) improved with both procedures, with earlier improvements noted in LRYGB that stabilized and did not differ from LVSG at 12 months postoperatively. Early improvements in measures of insulin resistance in both procedures were also noted in the studies that investigated this.

conclusionsThis systematic review of RCTs suggests that both LVSG and LRYGB are effective in resolving or improving preoperative type 2 diabetes in obese patients during the reported 3- to 5-year follow-up periods. However, further studies are required before longer-term outcomes can be elucidated. Areas identified that need to be addressed for future studies on this topic include longer follow-up periods, standardized definitions and time point for reporting, and financial analysis of outcomes obtained between surgical procedures to better inform procedure selection.
