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

objectiveTo investigate the correlation between the vitamin A, D, and E levels and recurrent respiratory tract infections (RRTIs) in children of different ages.

methodsA total of 150 RRTI patients were divided into three groups: the 0 to 2 year-old group, the 3-5 year-old group, and the 6-14 year-old group. Collectively, we refer to the three groups as the RRTI group. The serum vitamin A, D and E levels were measured in the three groups. Healthy children without RRTIs were recruited as a control group. The correlations between the changes in the vitamin A, D, and E levels and the RRTIs were analyzed.

resultsThe vitamin A, D, and E levels decreased significantly in the children with RRTIs, but only the vitamin A and D levels were negatively correlated with the incidence of RRTIs, while the vitamin E levels were not significantly correlated with the incidence of RRTIs. The follow-up results showed that the serum vitamin A, D, and E levels in the RRTI group were significantly increased after the treatment, and the WBC and CRP levels were remarkably reduced.

conclusionMonitoring the serum vitamin A and D levels helps determine the disease severity, and the supplementation of adequate vitamin A and D through diet or drugs is of great help in treating RRTIs.
