Hi and thank you very much for the amazing work. QUESTION: why in hell my title crossbars don't show the negative part of the bar? I've tried everything, including "show both sides" obv... I feel like my excel is just bugged sometimes, like when I select a series of values or bars in the graph not all of them appear selected (light blue dots around them) but the actually modify if I change values 😅. I'm lost guys😞
Hello, I must say you have done a great job. When I am opening the gui for abstract screening, the title and abstract cells are empty. I have downloaded the data from the Scopus database as a CSV file. Can you please help me?
I had the same problem today with the abstract screener, but here the solution: 1. Open the excel that has the data. 2. Click on file. 3. Click on Save As. 4. Save the file as CSV(coma delimited) (*.csv)
thank you for making this, i am a master student trying to do a literature review and meta analysis for my masters thesis project and to follow what you do makes it more clear what i should be focusing on, and makes it less intimidating!
Thank you! Very useful. How do we get those d and variance from literatures? For example, I got the OR=1.25 (group treatment vs control), then what is the d and variance here?
This is amazing! I’m from brazil and learning to start a research. You are by far The best that i have found. Thank you for sharing such a rich content in a free platform. The world thanks you 😊
I am new to this meta-analysis thing and as a student your videos have been very helpful, I have been watching a lot of videos that summarise the process, but the truth is when you are a first timer you need the whole process to be explained. Your examples of extraction were very helpful. Thank you for self-sacrificing your time for us.
Hey, Mark. I don't usually comment on RU-vid videos but you're an exception. I was absolutely clueless about writing the result section of my meta-analysis before this but now I am not. This was very helpful. Thank you so much!
Great content! Regarding data extraction for meta-analysis, let's say in a two-factor study with warming (T) and nitrogen addition (N), how many pairings can I form, apart from C(control) and T, C and N? What about TN and CN, TN and CT? Should I be concerned about double counting?
Hi Marc, I have been working for over 19 years in evidence synthesis in health care, mostly performing lit reviews and meta-analyses. I have been using web application of plot digitizer for years. I also came across digitize package in R, but never used that. I saw this video today and feel I can automate plot digitization with juicer. I am wondering if you have a peer reviewed publication on the precision of this package? And yes, I have to digitize survival curves (Kaplan Meier plots) mostly.
Okay, I just installed and ran one KM plot through it. Seems its completely unable to identify the KM plot, reading that like a scatter plot. Seems may not be useful for my purpose 😔
It's my plan this summer to update the package (with more ways to automate curves, like KM plots) and submit for publication -- sigh, so much to do, so little time 🙂
This video and the rest of the series have been fantastic and so helpful. Thank you! Your passion for this topic is clearly evident as well, which makes it that much better. Is there a way to make funnel plots for publication bias through Excel? Not sure if you made a video on this already, but I didn't see one. Thanks again for uploading these!
Hi! I have seen you replicate rows in your data set (therefore replicated study names) as each row is dedicated to the results for a "variation" in the experimental procedure, for example, a different dosage of the compound (each replication has a different dose). When you run your data-set through R studio, don't you get replicated study names as well? I am having this problem and do not know what to do.
When I have something I want to read or I know it's grey literature and not relevant to the review I usually use a "G" against it and use excel to pull them out separately
This is amazing, thanks for sharing these videos! These have been helpful in trying to develop new systematic processes in work to streamline and reduce human error in our systematic literature reviews.
juicr package for R seems the best free semi-automatic graph digitizer program for converting plots, graphs, charts and, who knows, maybe topographic and bathymetry maps (after preprocessing) into data points. And written by an ecologist, as I learned. It's just unbelievable judging by the video
I am currently working on my docoral dissertation for my clinical psycholog program. I am planning to do a meta-analysis to see the effect that exercise has on alleviating the symptoms of depression. However, there is tons of research out there (thousands of articles found on PubMed, PsychInfo, and NICAHL). Any tips on how to screen them? Any advice would help.
