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

Background: Controversial data on the effects of vitamins (V) and nutrients on the management of type 2 diabetes mellitus (T2DM) is available. Thus, it is aimed to clarify the role of vitamins and nutrients through an umbrella review regarding the available observational/ trials meta-analyses. Methods: All meta-analyses of observational and clinical trials conducted on the impact of vitamins and nutrients in T2DM published until 5 Results: The overall of 93 papers (99 studies) consisting of 75 trials and 24 observational studies were included. Most studies were conducted on the effect of VD and alpha-lipoic acid (ALA) in both genders. Consumption of VD or its analogous; 20 IU/d to 450,000 IU/once for 3 weeks to 7 years showed to have a positive effect on the parameters of glucose hemostasis. Moreover, an inverse association was observed between VD level and T2DM risk. Daily consumption of 1200 mg VC for at least 12 weeks improved lipid profile and glucose hemostasis parameters. Furthermore, VB and medications for diabetic polyneuropathy (DPN) increased nerve conduction velocity. Vitamins K and E were showen to not have significant impact on T2DM. ALA had a beneficial effect on DPN symptoms after 2-4 weeks of intake of at least 300 mg/d. T2DM risk was reduced by doubling ALA intake. The effective daily doses of chromium, zinc and coenzyme Q10 on lipid profile and glucose hemostasis parameters were > 200 mg, < 25 mg, and < 200 mg, respectively. Conclusion: This umbrella review suggests that dietary vitamins and nutrients can result in protective impacts the complications associated with T2DM. However, due to discrepancies between the results of the trials and observational studies is essential to conduct long-term high-qualified studies to prove the beneficial therapeutic effects of the vitamins and nutrients on T2DM and its complications.
