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

backgroundUrinary iodine concentration (UIC) is related to prediabetes and diabetes; nevertheless, there is still a dearth of data about the association of UIC with all-cause mortality in diabetics.

objectiveTo investigate the connection between UIC and all-cause mortality in diabetics.

methodsData from NHANES, collected on adult Americans between 2005 and 2018, were used in this investigation. The associations between ln-transformed creatinine-adjusted UIC (urinary iodine/creatinine, UI/Cr) and all-cause mortality in diabetics, as well as in older diabetics with a history of thyroid disease, were analyzed using Cox proportional hazards models and survival curve analysis. Subgroup analyses and interaction tests were conducted to examine variables affecting the association between ln(UI/Cr) and all-cause mortality in people with diabetes. Lastly, the effect of smoking on this association was tested by using restricted cubic spline (RCS).

resultsA total of 2,141 participants were included in this study. ln(UI/Cr) was significantly associated with a higher risk of all-cause mortality in diabetics in the unadjusted model (HR= 1.38, 95% CI: 1.20 - 1.58, P<0.001), but this association lost significance when confounding variables were considered (P> 0.05). Subgroup analysis revealed that Mexican-Americans and females had a stronger positive connection (P<0.05) between ln(UI/Cr) and the risk of all-cause mortality among diabetics. There was a significant correlation between ln(UI/Cr) and mortality in female smokers with diabetes (95% CI: 1.16 - 2.18, P=0.004). The RCS analysis demonstrated a significant non-linear relationship (P-non-linear= 0.0131). ln(UI/Cr) was significantly and positively associated with all-cause mortality in elderly diabetic individuals with a history of thyroid disease (HR= 1.38, 95% CI: 1.01 - 1.87, P=0.042).

conclusionIn American individuals with diabetes, our research validates the association between UI/Cr and all-cause mortality. This correlation might offer additional dietary suggestions for the management of individuals with diabetes.
