Validity of self-reported vitamin D deficiency among midlife Arab women living in Qatar.

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.
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
objectivesThis study evaluates the level of agreement between self-reported vitamin D deficiency and serum vitamin D measured within the previous calendar year.
methodsIn a study in which serum 25(OH)D levels were retrieved from electronic health records, 523 women were asked whether they considered themselves to have vitamin D deficiency. Serum vitamin D levels were categorized as vitamin D deficiency if serum 25(OH)D was <20 ng/ml and as insufficiency if <30 ng/ml. The kappa statistic was computed to assess the level of agreement between serum 25(OH)D level and self-report responses.
resultsAgreement between self-reported and measured 25(OH)D levels was poor. The kappa statistic was -0.041 when using a cutpoint of <20 ng/ml and -0.008 using the cutpoint of <30 ng/ml. Among women with levels ≥20 ng/ml, 82.4% believed that they were vitamin D deficient, while 13.3% who were below <20 ng/ml did not self-report deficiency. Among women who did not report vitamin D deficiency, 46.3% (37/80) had levels <20 ng/ml while 82.5% (66/80) had levels <30 ng/ml.
conclusionsThese findings suggest that, although the prevalence of 25(OH)D <20 and <30 ng/ml was quite high (53.2% and 84.7%, respectively), there was little agreement between measured levels and self-report of vitamin D deficiency. This may be due to belief in this region that low levels of serum vitamin D is widespread. Better communication is needed between healthcare providers and patients regarding transmission of laboratory results.
