Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Review Description
Aims: The present study evaluated the effect of oral zinc supplementation on shortening hospital length of stay. Methods: A systematic review was conducted for randomized control trials in patients who were hospitalized regardless of age and cause of admission. Studies were collected from PubMed, Web of Science, SCOPUS, and the Cochrane Library until July 2023. Results were compared between the zinc group and those who received a placebo and/or the standard therapy. Results: Eight studies were qualified for our meta-analysis. Of the 1267 patients, 633 and 634 were in the zinc supplementation and control groups, respectively. The meta-analysis found that oral zinc supplementation group experienced a lower length of hospital stay than the control group (mean difference, −0.43 days; 95% confidence interval, −0.65 to −0.22; P < 0.0001; heterogeneity, I = 20%). Conclusion: The administration of oral zinc supplements was associated with a slightly reduced duration of hospital stay.
