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

introductionMany risk prediction models of diabetes remission after bariatric and metabolic surgery have been proposed. Most models have been created using Roux-en-Y gastric bypass cohorts. However, validation of these models in sleeve gastrectomy (SG) is limited. The objective of our study is to validate the performance of risk prediction models of diabetes remission in obese patients with diabetes who underwent SG.

methodThis retrospective cohort study included 128 patients who underwent SG with at least 1 year follow-up from Dec 2011 to Sep 2016 as the validation cohort. A literature review revealed total 11 models with 2 categories (scoring system and logistic regression), which were validated by our study dataset. Discrimination was evaluated by area under the receiver operating characteristic (AUC) while calibration by Hosmer-Lemeshow test and predicted versus observed remission ratio.

resultsAt 1 year after surgery, 71.9% diabetes remission (HbA1c < 6.0 off medication) and 61.4% excess weight loss were observed. Individual metabolic surgery, ABCD, DiaRem, Advanced-DiaRem, DiaBetter, Ana et al., and Dixon et al. models showed excellent discrimination power (AUC > 0.8). In calibration, all models overestimated diabetes remission from 5 to 30% but did not lose their goodness of fit.

conclusionThis is the first comprehensive external validation of current risk prediction models of diabetes remission at 1 year after SG. Seven models showed excellent predicting power, and scoring models were recommended more because of their easy utility.
