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: Grip strength is a key marker for sarcopenia screening, yet the influence of iodine nutritional status on low grip strength (LGS) remains poorly understood. Methods: This cross-sectional study analyzed 810 community-dwelling adults in Lanzhou, China, randomly assigned to training ( Results: LGS prevalence was 18.8% in the training cohort. Multivariate analysis showed female sex (OR = 0.34), greater height (OR = 0.94), and excessive iodine (OR = 0.36) were inversely associated with LGS, whereas age (60-74 years: OR = 2.20; ≥75 years: OR = 9.73), smoking (OR = 3.20), and SP (OR = 1.02) correlated with higher LGS odds. The nomogram demonstrated moderate discrimination (AUC: 0.723 training, 0.662 validation) with good calibration (Brier scores: 0.134 training, 0.147 validation; H-L Conclusion: The nomogram provides a practical, objective tool for early identification of individuals at high probability of LGS. Moderate-to-high UIC is associated with LGS odds, particularly in euthyroid adults. This model may guide targeted screening and interventions in community settings. In the cross-sectional design, causal inferences cannot be drawn; Further research is warranted to elucidate these complex relationships.
