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

unlabelledThe present prospective follow-up study among 1,393 community-dwelling elderly women aged 75 years or older was conducted to clarify the association between serum 25-hydroxyvitamin D (25(OH)D) level and risk of falls. Lower serum 25(OH)D, particularly level <20 ng/mL, was significantly associated with an increased risk of falls.

introductionSerum 25(OH)D level has been revealed to be important factor not only for skeletal health but also for fall prevention among the elderly. Our previous cross-sectional study indicated that low serum 25(OH)D level is associated with inferior physical performance and falls among elderly Japanese women. The present prospective study was designed to clarify the association between serum 25(OH)D level and risk of falls before and after 1 year of follow-up.

methodsThe community-dwelling elderly women aged 75 years or older (N = 1,393) who participated in a mass health examination were followed 1 year later by a mailed self-administered questionnaire.

resultsResponses were obtained from 1,285 subjects (response rate = 92.2%). The incidence of falls at baseline and at 1-year follow-up was 18.8 and 24.4%, respectively. The baseline prevalence of serum 25(OH)D <20 ng/mL was 35.2%. Odds ratios (95% confidence intervals) in the lowest tertile of serum 25(OH)D (<20 ng/mL) compared with those in the highest tertile (≥25 ng/mL) were 1.40 (1.01-1.94) for any falls and 1.47 (0.93-2.32) for recurrent falls vs. no falls adjusted for potential risk factors.

conclusionsAmong elderly Japanese women, the lower serum 25(OH)D, particularly level <20 ng/mL, was significantly associated with an increased risk of falls.
