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

introductionBone fragility is a known complication of type 1 diabetes (T1D) and because DXA provides areal rather than volumetric bone mineral density (BMD), height-for-age adjustment offers a more accurate assessment of bone density.

aimsTo evaluate HAZ-adjusted BMD z-scores (BMD z-scores adjusted for height-for-age [HAZ]) in youth with T1D and identify factors associated with height-adjusted bone density.

methodsThis cross-sectional study included youth aged 8-17 years with T1D ≥1 year underwent DXA; T1D-related history, anthropometrics, dietary intake, and 25-hydroxyvitamin D [25(OH)D] were analyzed in association with HAZ-adjusted BMD z-scores.

resultsA total of 124 youth participated (mean age 12.9 ± 2.5 years; BMI z-score 0.67 ± 0.81; HAZ 0.25 ± 0.96; diabetes duration 6.0 ± 3.2 years; HbA1c 8.1 ± 1.1%). Mean daily intake was 8.7 ± 9.0 μg vitamin D, 1011.1 ± 464.7 mg calcium, and 1.5 ± 0.6 g/kg/day protein; recommended dietary allowance targets were met by 17%, 23%, and 85%, respectively. Vitamin D status was 9% deficient, 48% insufficient, and 43% sufficient. Mean HAZ-adjusted BMD z-score was -0.36 ± 1.01, significantly lower than the reference data (p = 0.0001). BMD z-scores correlated with BMI z-scores (r = 0.27, p = 0.002) and 25(OH)D (r = 0.25, p = 0.005). The vitamin D-deficient group had significantly lower HAZ-adjusted BMD z-scores than both the insufficient and sufficient groups (Δ = 1.06, p = 0.004; Δ = 1.02, p = 0.004). No associations were observed with diabetes duration, HbA1c, or dietary intake of vitamin D, calcium, or protein.

conclusionsYouth with T1D had lower HAZ-adjusted BMD compared with the reference population, and HAZ-adjusted BMD was associated with BMI z-scores and 25(OH)D levels. Maintaining healthy weight and adequate vitamin D levels remains important for bone health in this population.
