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

Implantable intravascular continuous blood glucose monitors (CBGMs) offer a promising approach for accurately measuring glucose levels with short lag times and improved reliability when compared with conventional laboratory-based point-of-care or handheld glucometers. In this study, 34 Glucotrack long-term intravascular CBGM devices were implanted into 17 adult sheep, with one device placed in each jugular vein. Each implantation was completed in approximately 20 min and did not require any customized tools or techniques. Intravenous glucose tolerance tests (IVGTTs) were performed approximately monthly throughout the studies (30-240 days postimplantation) and mean absolute relative difference (MARD) values were calculated against an Accu-Chek Guide handheld glucometer as the reference standard. The weighted average MARD was 6.84% for all 34 devices during a total of 79 IVGTTs. In addition, no device-related adverse safety events were observed during this long-term in vivo proof-of-concept evaluation.
