A randomized clinical trial to assess the effect of zinc and vitamin D supplementation in addition to hypertonic saline on treatment of acute bronchiolitis.
Trial report in BMC infectious diseases, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT05795933 (Efficacy of Vitamin D Supplementation for Children With Bronchiolitis at Sohag University Hospital), which is not on this map. Cited by 4 papers.
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.

Abstract
backgroundBronchiolitis, the most common cause of hospitalization in infancy has not yet a definitive treatment. This study was conducted to assess the effect of Zinc and vitamin D on treatment of infants with bronchiolitis.
methodsIn this double blind, randomized clinical trial, 94 infants aged 2 to 23 months, admitted in Mousavi Hospital in Zanjan, Iran, with the diagnosis of acute bronchiolitis were randomly assigned into 3 groups. The control group was only treated with hypertonic saline. The two case groups received either 100 unit/kg/day of Vitamin D or 20 mg/day of zinc in addition to hypertonic saline. Wheezing, duration of hospital stay, cough, cyanosis, respiratory distress and the respiratory rate in the first, third and seventh day of hospitalization were evaluated.
resultsThere was no significant difference between groups in terms of age, sex, weight, passive smoking, wheezing, oxygen saturation, cyanosis and type of delivery. On the third day of hospitalization, the respiratory rate/min in the control group, the groups receiving vitamin D and zinc were 45.2 ± 10.7, 37.8 ± 3.9 and 41.1 ± 9.1 respectively and the result of repeated measure analysis didn't show any significant difference between the 3 groups (P = 0.562). Duration of hospitalization in the group receiving Vitamin D or zinc and in controls were 4.2 ± 2.6, 4.4 ± 2.2 and 5.1 ± 2.4 days respectively and this difference was not significant. Zinc receiving patients did not differ from the control group regarding to respiratory rate, cyanosis and wheezing.
conclusionVitamin D or zinc administration was not effective in reducing respiratory rate in children with bronchiolitis. Trial registration This project was approved by the Institutional Ethics Committee (IR, ZUMS.REC.1396.50), and registered on IRCT (IRCT20131217015835N7).
