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

backgroundorthostatic hypotension (OH) that occurs within, or at, 1 minute of standing is associated with higher risk of falls, myocardial infarction, syncope and mortality, compared to OH that occurs after 1 minute of standing. Whether vitamin D deficiency increases the risk of OH is controversial.

methodsthis was a cross-sectional analysis of 3,620 older, community-dwelling men. Multinomial, multiple logistic regression models were used to calculate the risk of OH across categories of vitamin D status (deficient [<25 nmol/l], insufficient [≥25-<50 nmol/l] and sufficient [≥50 nmol/l]) and parathyroid hormone quintile.

resultsmen with vitamin D deficiency were more likely to have OH that occurred within 1 minute of standing in univariate logistic regression (OR 1.88, 95% CI 1.40-2.53) and multinomial, multiple logistic regression (OR 1.51, 95% CI 1.06-2.15), compared to men with sufficient levels of vitamin D. Vitamin D insufficiency was not associated with the risk of OH. Elevated parathyroid hormone was not associated with risk of OH.

conclusionthe absence of an association between vitamin D insufficiency and risk of OH and the presence of an association between vitamin D deficiency and risk of OH suggest that there may be a threshold effect; it is only below a particular level of vitamin D that risk of OH is increased. In this cohort, the threshold was <25 nmol/l. Future work should investigate whether treating vitamin D deficiency can improve postural blood pressure or if preventing vitamin D deficiency reduces the incidence of OH.
