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

objectivesTo study prevalence and determinants of vitamin D deficiency in immigrants from Africa and the Middle East living in Umeå, Sweden.

designCross-sectional population based.

settingUmeå, Sweden (63° N). SUBJECTS/

methodsImmigrants aged 25-65 years from nine countries in Africa or the Middle East (n=1306) were invited. A total of 111 men and 106 women (16.5%) completed the study. S-25-hydroxyvitamin D3 was measured with HPLC. Anthropometry, medical, socioeconomic and lifestyle data were registered.

resultsVitamin D status was insufficient or deficient in 73% of the participants. Specifically, 12% had vitamin D deficiency (25(OH)D3<25 nmol/l), and only 3.7% had optimal vitamin D status (25(OH)D3 75-125 nmol/l). Mean 25(OH)D3 level was 41.0 nmol/l (± 16.6) with no difference between sexes. Levels of 25(OH)D3 were lower (P=0.030) and vitamin D deficiency was twice as common in immigrants from Africa compared with those from the Middle East. In the multiple regression analysis, vitamin D deficiency was significantly associated with low fatty fish intake (OR 4.31, 95% CI 1.61-11.55), not travelling abroad (OR 3.76, 95% CI 1.18-11.96) and wearing long-sleeved clothes in summer (OR 3.15, 95% CI 1.09-9.12).

conclusionsThe majority of immigrants from Africa and the Middle East who live in northern Sweden have vitamin D deficiency or insufficiency. Our results are consistent with sun exposure and a diet with high intake of fatty fish being most important in avoiding vitamin D deficiency.
