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

backgroundObesity increases the risk of diabetic peripheral neuropathy (DPN). However, past studies have typically assessed obesity using anthropometric measurements. Our primary aim determined associations between detailed obesity measurements, DPN, and painful DPN (pDPN). Our secondary aim compared the discriminatory capabilities of these measurements.

methodsWe performed a cross-sectional study of persons with diabetes. Obesity was assessed using anthropometrics, bioelectrical impedance (BIA), abdominal MRIs (aMRI), and/or dual x-ray absorptiometry (DEXA). Obesity measurements were categorized as measuring general, central, or peripheral obesity, or the central-peripheral obesity ratio. DPN was defined as Michigan Neuropathy Screening Instrument questionnaire ≥ 4. Within this group, pDPN was defined as bilateral foot pain in the prior 3 months. Areas under receiver operating characteristic curves (AUC) determined discriminatory capabilities of obesity measurements for DPN, stratified by sex.

resultsWe identified 7090 persons with diabetes that completed DPN assessments (mean age: 58.4, 39.6% female), of which 100.0% completed anthropometrics, 98.4% completed BIA, 3.9% completed aMRI, and 2.3% completed DEXA. 1271 (17.9%) had DPN with 28.1% experiencing pDPN. Logistic regression revealed 13/13 anthropometric, 27/29 BIA, 21/34 DEXA, and 8/14 aMRI measurements associated with DPN, but none associated with pDPN. For males, median AUCs for DPN were similar regardless of location (central: 0.88, 0.89, general: 0.89, peripheral: 0.88, central-peripheral ratio: 0.87), whereas for females, central obesity (0.92) had the largest AUC for DPN, followed by general (0.88), peripheral (0.84), and central-peripheral obesity ratio (0.78).

conclusionsObesity is associated with DPN, but not pDPN. For males, obesity distribution did not differentially discriminate DPN, whereas for females, central obesity best discriminated DPN.
