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

purposeIn this study, we aimed to determine whether short-term (2 months) vitamin D supplementation could improve the allergic symptoms in AR patients.

methodsA randomized double-blind placebo-controlled clinical trial was performed on allergic rhinitis patients with vitamin D deficiency from Nov. 2017-2018. 80 cases with allergic rhinitis and vitamin D deficiency were divided into two groups and vitamin D plus routine antihistamine medication (cetirizine) was prescribed for the study group, whereas the control group received cetirizine plus placebo. The clinical symptoms questionnaire was completed at baseline and after 4 and 8 weeks of treatment initiation. Vitamin D levels were re-measured at the end of the 8-week treatment course.

resultsIn total, 80 patients with allergic rhinitis and vitamin D deficiency were enrolled. Among them, 35 cases and 33 controls visited the clinic after 8 weeks; the mean age in the aforementioned groups was 29.68 years and 29.13 years demonstrating no meaningful difference (P > 0.05). At study initiation, the mean vitamin D level was 14 ng/ml and 14.67 ng/ml in the study and control groups, respectively, indicating no significant difference (P = 0.189). The mean serum vitamin D level at 8 weeks of treatment in the study group (24.08 ng/ml) indicated a statistically meaningful difference with the mean vitamin D level at baseline (P < 0.001). Comparison of the mean scores of symptoms severity showed no significant difference between the two groups at study initiation and 4 weeks later (P = 0.073), whereas a significant difference was obtained between baseline and 8 weeks of treatment initiation (P = 0.007).

conclusionBased on the findings of the present study, it can be concluded that vitamin D supplementation along with antihistamines can result in relative symptoms improvement in AR patients with vitamin D deficiency.
