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

purposeNo previous study has evaluated the relationship between vitamin K and frailty. Thus, we assessed the relationship between vitamin K status and frailty over 13 years in the Longitudinal Aging Study Amsterdam (LASA).

methodsProspective cohort study with 644 community-dwelling adults ≥ 55 years from the LASA cohort. In 2002-2003, plasma desphospho-uncarboxylated matrix Gla protein (dp-ucMGP) was measured as marker of vitamin K status through a sandwich ELISA. Frailty was measured at baseline and in four follow-up examinations with the LASA Frailty Index (LASA-FI), which was used as both a continuous and a dichotomous measure (FI ≥ 0.25), as indicator of the degree of frailty and frailty risk, respectively. Statistical analyses were performed with multivariable generalized estimating equations using the lowest dp-ucMGP tertile, reflecting a high vitamin K status, as reference.

resultsThe mean (SD) age was 59.9 (2.9) years, and 54% were female. Compared with the lowest tertile, the medium and highest dp-ucMGP tertile were associated with a higher degree of frailty [1.40, 95% confidence interval (0.01-2.81) and 1.62, (0.18-3.06), respectively. P trend: 0.03]. Additionally, the medium and highest dp-ucMGP tertile had a higher odds ratio of frailty [1.75 (1.11-2.77) and 1.63 (1.04-2.57), respectively]. The degree of frailty increased over time, but the differences by dp-ucMGP tertiles existed since baseline and remained stable during follow-up.

conclusionsBaseline plasma low vitamin K status was associated with a greater degree of frailty and frailty risk in this cohort of older adults, which highlights the importance of ensuring an optimal nutritional status of this vitamin to prevent frailty in later life.
