In that way, you’ll be able to utilize the latest technology of the OBD2 scanner while on the run. SF drafted the manuscript which was revised by all authors. All authors take responsibility for the accuracy and integrity of the work. We believe that sensitivity analysis is the key to ensuring that an analysis is robust.
You can see the live data displayed on the screen clear and bright. It comes in text, graph, and analog to make it easier for you to understand. The manufacturer offers a 12-month warranty and one-year free software update upon purchasing the product. Aside from diagnosing the vehicle, it also offers a repair solution. If you are clueless on how to repair your car after knowing what was troubling it, download the RepairSolution application and follow the step-by-step guide. One good thing about this device is that the manufacturer offers a free internet update.

MetaDTA allows users to upload their own data, analyses the data and presents the results in downloadable formats. We developed a user-friendly intuitive user interface which allows users to explore their data and the analysis. The application uses the statistically rigorous bivariate model to analyse the data and much of the data and results can be presented graphically via an interactive SROC plot.

- Therefore, using bivariate or HSROC models is more appropriate for MA of DTA studies .
- However, the Cochrane software RevMan uses the Moses-Littenburg method for DTA MA which does not properly take into account random effects and the correlation between sensitivity and specificity .
- Cochrane publish a number of diagnostic test accuracy reviews each year.
- A search of the Cochrane Database of Systematic Reviews on the 7th September 2018 identified 99 reviews of type ‘diagnostic’ published between October 2009 and August 2018.
- We encourage others to create similar applications for specialist analysis methods to encourage broader uptake which in-turn could improve research quality.
There are many options available allowing users to customise the graphs to suit their needs including the option to incorporate quality assessment results from the QUADAS-2 tool. In addition, all statistical parameter estimates are presented in tables with uncertainty. All tables and figures can be downloaded from the application. Furthermore, we encourage the use of sensitivity analyses by allowing users the option to remove trials from the analysis. Data on the quality of the primary diagnostic accuracy studies, evaluated using the QUADAS-2 tool , can be incorporated within SROC plots in MetaDTA.
However, some published meta-analyses of DTA studies may hypothesise about how their results could be affected by certain studies but don’t always conduct sensitivity analyses. Sensitivity analyses can be time-consuming and may involve ‘going back to the start’ and creating a new dataset excluding influential studies GIMP download and running the analysis again. A key element of sensitivity analyses is to assess the impact of study quality on the DTA MA results. MetaDTA allows the results of quality assessment from the QUADAS-2 tool to be included in the uploaded data file. An assessment of how the DTA MA results change when low quality studies are excluded can then be easily conducted by removing the low quality studies with results displayed visually in both figures and tables.
We believe that MetaDTA which allows customisable and statistically informative graphics could improve the conduct of sensitivity analyses. We created MetaDTA, an online interactive ‘point-and-click’ application for meta-analysis of DTA studies.
