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

introductionThis study investigated the relationship between serum 25-hydroxyvitamin D (25OHD) levels and the occurrence of hip fractures in the elderly using a systematic review and meta-analysis approach. MATERIALS AND

methodsPubMed, Web of Science, and Scopus were used to identify studies that outlined an association between serum 25OHD and the occurrence of a hip fracture in a geriatric patient. The analysis calculated odds ratios (OR) for a hip fracture using a random-effects model.

resultsIn this study, 28 studies were included, 61,744 elderlies and 9767 cases (15.81%) of hip fractures. In the lowest vs. highest categories of vitamin D in the elderly, pooled OR of hip fractures was 1.80 (95% CI 1.56-2.07, P ≤ 0.001), and modified OR was equal to 1.40 (95% CI 1.20-1.63 P ≤ 0.001). A subgroup analysis showed that the OR of a hip fracture was 2.16 (1.49-3.11, P ≤ 0.001) in case-control studies; 1.52 (1.29-1.79, P = 0.001) in cohort studies; and 1.41 (1.18-1.70, P ≤ 0.001) in case-cohort studies.

conclusionLow serum vitamin D levels in the elderly are associated with an increase in the odds of hip fracture.
