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

objectiveTo investigate the association between an almond-based low-carbohydrate diet (LCD) and continuous glucose monitoring (CGM) metrics in patients with type 2 diabetes mellitus (T2DM).

methodsThis was a prospective randomized controlled study. Hospitalized patients with T2DM from Changshu No.1 People's Hospital were recruited from January 2022 to December 2022. 33 patients using CGM were included and randomly divided into the low-fat diet (LFD) group or the LCD with almonds group based on the random number table. Primary CGM metrics including time in range (TIR), time in tight range (TITR), time above range (TAR), time below range (TBR) were compared between the two groups. Linear regression analysis was performed to assess the association between diet group and nocturnal glycemic metrics.

resultsCompared to LFD group, patients in the LCD with almonds group had higher nighttime TIR [98.51% (95.83, 99.88) vs. 91.67% (89.52, 98.07), P < 0.01] and TITR [94.14% (87.57, 98.41) vs. 77.58% (52.18, 90.58), P < 0.05]. Nighttime TAR [0.00% (0.00, 0.00) vs. 1.39% (0.00, 7.95), P < 0.01], HBGI [0.15 (0.01, 0.34) vs. 0.98 (0.08, 3.73), P < 0.05], and SD (15.57 ± 6.21 mg/dL vs. 23.62 ± 9.12 mg/dL, P < 0.05) were significantly lower in the LCD with almonds group. Multivariable regression demonstrated that LCD with almonds was independently associated with improvements in nocturnal TIR (β = 6.65%, P = 0.010) and TITR (β = 14.60%, P = 0.016) after adjustment for age, sex, and diabetes duration.

conclusionThe almond-based low-carbohydrate diet improved nocturnal glycemic control in patients with type 2 diabetes. These improvements in nocturnal TIR and TITR remained significant after multivariable adjustment for age, sex, and diabetes duration. CLINICAL TRIAL REGISTRY: The study was registered at clinicaltrials.gov (registration no. ChiCTR2600116495).
