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

unlabelledOBJECTIVE In a randomized trial, a guided diabetes peer support intervention improved glycemic control (A1c), with a difference in A1c change between groups of 0.58% (p = 0.004). The current study examined whether improvements in insulin uptake and perceived diabetes social support mediated the intervention's impact on A1c. We also examined potential moderation by patients' health literacy, diabetes social support, or diabetes distress. METHODS We conducted secondary analyses for 212 type 2 diabetes patients participating in the trial using accepted methods for testing mediation and moderation effects.

resultsRoughly half (49%, 95% CI: 3-80%) of the A1c effect was mediated by increased insulin use, while changes in diabetes social support had a negligible impact. A1c impacts varied across subgroups defined by baseline diabetes social support and functional health literacy (both p < 0.01). The intervention was particularly beneficial among patients with low baseline diabetes support or literacy levels. The intervention had a greater impact on A1c among patients with more frequent engagement in peer support calls (p < 0.01). DISCUSSION Patients receiving increased peer support had improved glycemic control largely due to their greater likelihood of initiating insulin. Greater intervention engagement was associated with stronger effects. The intervention had its greatest benefits among patients with low support or poorer health literacy.
