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

purposeDiabetic osteopathy is an upcoming complication of diabetes characterized by osteoporosis, increased risk for bone fractures and alterations in bone metabolism. Osteocalcin (OC) is a bone-specific protein produced by osteoblasts involved in the regulation of glucose and energy metabolism. The aim of this study is to determine whether OC serum levels are correlated with metabolic control in adult subjects with type one diabetes mellitus (T1DM).

methodsA cross-sectional study was conducted on 93 subjects (51 men) with mean age, disease duration and body mass index (BMI) of 39.9 ± 12.3, 17.2 ± 12.6 years and 24.5 ± 3.4 kg/m(2), respectively. Blood samples were drawn to measure levels of hemoglobin A1c (HbA1c), OC, 25-OH vitamin D and PTH.

resultsSignificant inverse correlations were found between OC and HbA1c (r = -0.295, P = 0.004) and between OC and BMI (r = -0.218, P = 0.037). These correlations were confirmed also among men in the analyses by gender [HbA1c vs OC: r = -0.363, P = 0.009; BMI vs OC: r = -0.291, P = 0.043], and similar but nonsignificant trends were confirmed among women. A significant difference in mean OC was also found between the lowest and the highest HbA1c tertile (22.3 ± 10.0 vs 16.9 ± 8.0 ng/mL, P = 0.025).

conclusionsThese data show that in T1DM of long duration, OC serum levels are inversely associated with HbA1c and BMI, supporting the hypothesis that a poor glycemic control can affect osteoblast function.
