Bedtime snacking and glycemic deterioration in young children with Type 1 diabetes on multiple daily injections: a randomized controlled crossover trial.
Trial report in Nutrition & diabetes, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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.
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 determine if a bedtime snack in young children with type 1 diabetes (T1D) prevents nocturnal hypoglycemia, and the impact on glycemia overnight.
methodsIn this randomized controlled crossover trial, 10 grams of carbohydrate (milk, yoghurt, and kefir) was given 150-180 minutes after dinner over three nights to 5-8-year-old children with T1D using multiple daily injection therapy. Continuous glucose monitoring (CGM) data were collected for 6 hours following the snacks on one control and three snack nights. Time in 70-180 mg/dL (3.9-10 mmol/L) range (TIR), time below 70 mg/dL (3.9 mmol/L) (TBR), and other metrics were analyzed according to international CGM consensus. Trial day was terminated if blood glucose exceeded 300 mg/dL (16.7 mmol/L) or fell below 70 mg/dL (3.9 mmol/L).
resultsOf 28 children (13 female, mean age 6.6 ± 0.8 years, HbA1c 7.0 ± 0.5% (53 mmol/mol)), mean glucose values before the test snacks were 137.8 ± 14.5 mg/dL (7.7 ± 0.8 mmol/L) for milk, 141.9 ± 16.9 mg/dL (7.9 ± 0.9 mmol/L) for yoghurt, 136 ± 19.1 mg/dL (7.6 ± 1.1 mmol/L) for kefir, and 140.8 ± 17.0 mg/dL (7.8 ± 0.9 mmol/L) for control without significant difference (p = 0.548). TIR was 34.7% for milk, 38.7%. for yoghurt, 45.9% for kefir, and 75.5% for control during the 6-hour post snack period, with TIR on the control day significantly higher than the three snack days (p < 0.001). TBR did not differ by group (p > 0.05). Of 112 trial days, 13 days were terminated due to hyperglycemia (>300 mg/dL) (16.7 mmol/L) (8 milk, 4 yoghurt, 1 kefir), and 3 trial days due to hypoglycemia (<70 mg/dL) (3.9 mmol/L) (1 yoghurt, 2 control).
conclusionBedtime snacking in young children with T1D impairs nocturnal glycemia and reduces TIR, without decreasing the frequency of hypoglycemia.
