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

AIMS/

introductionThis study aimed to assess the impact of switching from FreeStyle Libre (FSL) to FreeStyle Libre 2 (FSL2) with real-time continuous glucose monitoring (rtCGM) functionality. MATERIALS AND

methodsWe retrospectively assessed 58 patients who transitioned from FSL to FSL2 with rtCGM functionality.

resultsSwitching from FSL to FSL2 significantly increased the valid data acquisition rate (76.8% ± 21.6% vs 90.4% ± 18.0%, P < 0.001). Time in range (TIR) improved from 57.7% ± 18.1% to 61.7% ± 17.1% (P = 0.023); time in tight range improved from 33.3% ± 15.4% to 38.6% ± 16.9% (P = 0.006), and glycated hemoglobin decreased from 7.6% ± 1.1% to 7.4% ± 1.0% (P = 0.009). TIR improvement was immediate in Type 1 diabetes but gradual after an initial decline in Type 2 diabetes. Logistic regression identified younger age as a predictor of TIR improvement (odds ratio: 0.95, 95% confidence interval: 0.90-0.99, P = 0.034).

conclusionsTransitioning from FSL to FSL2 with rtCGM functionality improved valid data acquisition rate and glycemic control, particularly in patients with Type 1 diabetes. The duration required for improvement in continuous glucose monitoring-related parameters varied by diabetes type, with early improvements observed in Type 1 diabetes and gradual improvements in Type 2 diabetes.
