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

backgroundPregnant women with previous bariatric surgery are at increased risk of gestational diabetes mellitus (GDM) but many cannot safely tolerate the oral glucose tolerance test (OGTT). Consensus recommendations advise self-monitoring of blood glucose (SMBG) for GDM diagnosis, but diagnostic thresholds are unexplored in this population. STUDY

objectiveTo assess the incidence of SMBG-defined GDM (fasting, 1-hr postprandial thresholds: 90, 140 mg/dL (5.3, 7.8 mmol/L)) after bariatric surgery, compared to the incidence of OGTT-defined GDM in women with risk factors for GDM but no history of bariatric surgery. DESIGN AND

settingPatients with a history of bariatric surgery (n=24) were included in a retrospective service evaluation based at a single tertiary referral centre in England, with results compared to a national study of women at high risk of GDM but without a history of bariatric surgery (n=1,308).

main outcome measuresThe incidence of GDM diagnosed according to SMBG vs OGTT.

resultsGDM incidence was 16/24 (66.7%; SMBG-defined) after bariatric surgery and 121/1,308 (9.3%; OGTT-defined) in the control group, with the highest incidence rates seen after gastric bypass (85.7%). In women with previous bariatric surgery, HbA1c showed no association with GDM diagnosis, the requirement for treatment or offspring birth weight.

conclusionsSMBG at standard thresholds is not able to reliably diagnose GDM after bariatric surgery and is likely to over-diagnose GDM, especially after gastric bypass, although small sample size limits generalisability of this study. Alternative diagnostic and prognostic markers are warranted for diagnosis of GDM after bariatric surgery.
