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

aimsThis qualitative inquiry aimed to explore the lived experiences of pregnant women with self-management of type 1 diabetes (T1D) using closed-loop insulin delivery in the CIRCUIT trial

methodsWe used semi-structured, individual interviews with 18 CIRCUIT randomized trial participants. Two team members analysed verbatim transcripts using inductive thematic analysis.

resultsFour major themes emerged: 1. Independence and isolation; 2. Support is key; 3. Closed-loop impacts; and 4. Control and autonomy. Diabetes management during pregnancy was an emotionally overwhelming experience that was managed largely independently. Closed-loop was noted as a gamechanger for diabetes management during and after pregnancy. Participants felt the transition to and use of this technology would not have been possible without their healthcare team's support. Permeating all themes was the importance of control to achieve the best possible glycaemic outcomes for the health of their babies and autonomy over personal treatment decisions. The perceptions of loss of personal autonomy were associated with high anxiety.

conclusionsManaging T1D while pregnant is an independent and isolating endeavour, due to the 'invisible labour' involved and the lack of knowledge about T1D management in personal networks. Support from partners and care providers alleviated stress. Experiences with intrapartum care providers who had limited T1D understanding were perceived as a challenge by some for maintaining autonomy. The closed-loop system was seen as a 'gamechanger' in T1D pregnancy management, with unanimous perception of positive impacts that far outweigh any challenges. Use of this closed-loop system has potential to vastly improve pregnancy experiences among those with T1D.
