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

objectiveNutritional factors, especially the two essential nutrients calcium and vitamin D, have been shown to play an important role in bone health. We wanted to determine the possible protective effect of calcium intake in adequate amounts on bone mass as assessed by quantitative ultrasound in postmenopausal women who also have a high intake of selenium.

settingHealth district of Cáceres, Spain. PARTICIPANTS AND STUDY

design335 postmenopausal women aged 60.9 (SD = 8.1) years. Women were stratified based on the vitamin D, vitamin E, calcium intake and the calcium/protein and calcium/phosphorous index. MEASUREMENTS: Bone status (Ad-SoS measured at the phalanges) was assessed with an ultrasound device model DBM Sonic 1200R. Food intake was quantified using dietetic scales, measuring cups, and spoons based on 7 days of diet records. Urine samples were collected the morning of testing after an overnight fast. Venous blood samples for the hematological and biochemical studies were also obtained in the fasting state.

resultsIn the group of women with Ca intake < 800 mg / d we found a significant and negative relationship between Ad-SoS with age (β= -4.020, F = 23.327) and selenium intake (β = -0.419, F = 10.067), as well as a positive relationship with Ca intake (β= 0.104 and F = 7.084) (p <0.0001 in all). In the group of women with Ca intake > 800 mg / d, age has a significant and negative relationship (β = -4.829 and F = 106.745), whereas folic acid intake has a significant and positive relationship (β = 0.047 and F = 5.858) (p <0.0001 in both).

conclusionElevated selenium intake negatively affects bone mass measurements in postmenopausal women over the age of 51 but only if calcium intake is also less than 800 mg / day. When calcium intake is greater than 800 mg/day, selenium did not appear to affect bone mass.
