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

unlabelledData on the association between vitamin D status and osteoporotic fracture in Asians are sparse. We conducted a 6-year cohort study of 773 community-dwelling elderly Japanese women and found that serum 25-hydroxyvitamin D (25(OH)D) ≥ 71 nmol/L was associated with a reduced risk of osteoporotic limb and vertebral fractures.

introductionData on the association between vitamin D status and osteoporotic fracture in Asians are sparse. This study aimed to clarify the association between vitamin D and other markers of nutritional status with the incidence of fracture in elderly Japanese women.

methodsWe conducted a cohort study with a 6-year follow-up of 773 community-dwelling women aged 69 years and older. The 6-year follow-up ended in 2009. We assessed serum 25-hydroxyvitamin D, undercarboxylated osteocalcin (an index of vitamin K status), and calcium intake. The primary outcome was incident limb and vertebral fractures. Covariates were forearm bone mineral density (BMD), age, body mass index, osteoporosis treatment, and physical activity.

resultsThe mean serum 25(OH)D concentration was 60.0 nmol/L. Thirty-seven limb fractures and 14 vertebral fractures occurred in 4,392 person-years. Lower forearm BMD was significantly associated with increased incident fracture (P = 0.0242). The adjusted hazard ratios (HR) of fracture for the first quartile (<47.7 nmol/L) and the third quartile (59.2-70.9 nmol/L) of serum 25(OH)D, compared to the fourth quartile (≥71.0 nmol/L), were 2.82 (95% confidence interval (CI), 1.09-7.34) and 2.82 (95%CI, 1.09-7.27), respectively. The pooled adjusted HR was 0.42 (95%CI, 0.18-0.99) when the incidence in the fourth quartile (≥71.0 nmol/L) was compared to the other three quartiles combined (<71.0 nmol/L). Vitamin K status and calcium intake were not associated with incident fracture.

conclusionsSufficient vitamin D status, i.e., serum 25(OH)D ≥ 71 nmol/L, is associated with low limb and vertebral fracture risk in community-dwelling elderly women.
