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

aimsLimited studies have investigated glucose management around swimming in type 1 diabetes (T1D). This observational study of the Omnipod 5 Automated Insulin Delivery (AID) System assessed glycemic patterns and system operation with AID use during swimming. MATERIALS AND

methodsA total of seven swimmers (aged 11 ± 2 years, 57% female) with T1D recorded their swims using an activity tracker and completed online surveys after swims.

resultsParticipants reported 124 swims lasting 23-146 min. Median (IQR) starting glucose was 133 (93-178) mg/dL, with a change of -17 (-61 to 7) mg/dL during swims. Carbohydrate intake 2-h before swims was 20 (0-32) grams. Starting glucose ≥ 181 mg/dL showed the largest glucose decreases [-86 (-111 to -25) mg/dL] during swims. Activity feature was used in 87% of swims with a starting glucose < 90 mg/dL. Automated Mode was maintained for 98% (95%-100%) of swim time with 58% (24%-70%) of this time in Automated Mode: Limited.

conclusionsSwimming with AID was associated with generally modest declines in glucose. The Omnipod 5 System largely preserved automation in water (often via Automated Mode: Limited) without reverting to Manual Mode. Starting glucose dominated glycemic trajectory, with larger declines but low hypoglycemia risk at a higher starting glucose, and smaller changes, but more hypoglycemia at a lower starting glucose. Insulin suspension was not enough to reliably prevent hypoglycemia when starting glucose was < 180 mg/dL, highlighting the need for proactive carbohydrate intake with a lower starting glucose, even with AID.
