Changes will include providing more flexibility when using imported data, such that import can be used in more cases and eliminating some of the drawbacks of using DirectQuery. The set of capabilities offered by Power BI for import and DirectQuery evolve over time. Additionally, the list of limitations for the use of DirectQuery should be considered carefully. However, using DirectQuery is only feasible when the underlying data source can provide interactive queries, less than 5 seconds for the typical aggregate query, and can handle the query load that will be generated.

For example, if the data is changing frequently and reports must reflect the latest data, DirectQuery may be best. If your goals can't be met by importing data, consider using DirectQuery.Importing takes advantage of the high performance query engine of Power BI, and provides a highly interactive and fully featured experience. You should import data to Power BI wherever possible.Guidance for when you should consider using DirectQuery rather than importįollow best practices for using import versus DirectQuery:.

Severe adverse events were rare among treatment trials and evidence of no difference was assessed as low certainty. Low-certainty evidence suggested that there may be no benefit with ivermectin for "need for mechanical ventilation," whereas effect estimates for "improvement" and "deterioration" clearly favored ivermectin use. Secondary outcomes provided less certain evidence. Low-certainty evidence found that ivermectin prophylaxis reduced COVID-19 infection by an average 86% (95% confidence interval 79%-91%).

This was also robust against a trial sequential analysis using the Biggerstaff-Tweedie method.

This result was confirmed in a trial sequential analysis using the same DerSimonian-Laird method that underpinned the unadjusted analysis. Meta-analysis of 15 trials found that ivermectin reduced risk of death compared with no ivermectin (average risk ratio 0.38, 95% confidence interval 0.19-0.73 n = 2438 I2 = 49% moderate-certainty evidence). Twenty-four randomized controlled trials involving 3406 participants met review inclusion. Meta-analyses were conducted and certainty of the evidence was assessed using the GRADE approach and additionally in trial sequential analyses for mortality. Two review authors sifted for studies, extracted data, and assessed risk of bias. We searched bibliographic databases up to April 25, 2021. We assessed the efficacy of ivermectin treatment in reducing mortality, in secondary outcomes, and in chemoprophylaxis, among people with, or at high risk of, COVID-19 infection. The antiparasitic ivermectin, with antiviral and anti-inflammatory properties, has now been tested in numerous clinical trials. Repurposed medicines may have a role against the SARS-CoV-2 virus.
