Eine Meta-Analyse von 23 Studien wurde durchgeführt

Using this phrase requires a bit of 'grammatical gymnastics' because of the passive voice. The structure is: [Subject] + [Number of studies] + wurde durchgeführt. You can swap out the number 23 for any other number. Just remember that numbers in German can be tricky. For academic contexts, we usually write the digits. The verb wurde is the past tense of 'to be' in the passive sense. It goes in the second position of your sentence. The heavy hitter, durchgeführt, always waits at the very end. This creates a 'bracket' that holds the information together. If you are writing a report, start with this to set the stage. If you are speaking, use it to ground your argument in reality. It is a very 'static' phrase. It describes a completed action that stands as a fact. Think of it as a solid brick in the wall of your presentation.

This phrase lives in the 'Very Formal' neighborhood. You will find it in university hallways and scientific journals. It is the language of the Tagesschau (the famous German news). You wouldn't use this at a casual BBQ unless you want to be 'that person.' It is the C1 level's way of showing you mastered the passive voice. In German culture, being precise is a form of respect. Using durchgeführt instead of gemacht shows you respect the scientific process. It is a 'high-register' expression. It signals that you are an expert or at least a very serious student. Even if you aren't a scientist, using it in a job interview shows you value data. It is polished, clean, and very 'German' in its efficiency. Just don't use it in a WhatsApp group with friends. They might think you've been replaced by a research robot.

You will see this in news articles about health or climate change. Headlines love this phrase because it adds instant credibility. 'A meta-analysis was conducted' sounds much better than 'We looked at stuff.' On LinkedIn, a data scientist might post this to show off a new project. In a university lecture, a professor will use it to summarize a field of study. You might even see it on a serious documentary on Netflix or YouTube. If you are watching a German tech review, the host might use it to compare batteries. It also appears in government reports and white papers. Basically, anywhere where facts are more important than feelings, this phrase is there. It is the language of the informed citizen. It shows you are part of the 'educated elite' who actually reads the fine print. It is a badge of intellectual honesty.

Use this when you are writing a master's thesis or a formal essay. It is perfect for the 'Methodology' section of a paper. Use it during a PowerPoint presentation to back up your claims. If you are in a high-level business meeting, it can justify a big decision. It is great for responding to a skeptical boss who wants 'proof.' You can also use it in a formal email to a professor. It shows you've done your homework. Use it when you want to shift the focus from yourself to the data. It is the best way to introduce a complex topic. If you are blogging about science or psychology, this is your bread and butter. It makes your blog post look like a peer-reviewed journal. Use it whenever you need to sound like the smartest person in the room. Just make sure the data actually exists first!

Do not use this to describe your weekend plans. Saying 'A meta-analysis of three bars was conducted' will get you weird looks. Avoid it in casual texts or voice notes to your best friend. It is too 'stiff' for a romantic date, unless you both love statistics. Do not use it if you only looked at one study. That is just a regular analysis, not a 'meta' one. Don't use it if you are unsure about the passive voice. If you mess up the word order, the authority of the phrase vanishes. Avoid it in children's books or very simple explanations. It is too complex for a beginner's level. Do not use it to exaggerate simple things. It's for serious research, not for deciding which Netflix show to watch next. Keep it in its academic box.

The most common error is forgetting the 'n' in Studien. In German, the plural of Studie is Studien. People also often try to use the active voice and get confused. They might say Ich habe eine Meta-Analyse durchgeführt, which is fine, but less formal. The biggest 'no-no' is using gemacht instead of durchgeführt. It sounds like you did the analysis with a crayon. Another mistake is putting durchgeführt in the wrong place. In a main clause, it must be the very last word. Don't forget the ge- prefix on durchgeführt. Some learners say durchführt, which is the present tense. That changes the whole meaning. Accuracy is key here. If you are going to use a fancy phrase, you have to nail the details.

You can change the subject of the sentence easily. Instead of studies, you could talk about Experimente (experiments) or Umfragen (surveys). You can also change the verb to veröffentlicht (published). For example: Die Ergebnisse wurden in 23 Studien veröffentlicht. If you want to be slightly less formal, you can use erstellt (created). In a more modern, digital context, you might hear ausgewertet (evaluated). Younger researchers might say Wir haben die Daten von 23 Studien gebündelt. This is more 'active' and 'fresh.' In South Germany or Austria, you might hear slightly different sentence rhythms. However, in written German, the standard version is universal. It is the 'Gold Standard' for academic reporting across all German-speaking countries. It doesn't really go out of style.

Is this phrase only for scientists? No, anyone can use it to cite data. Is the word 'von' always necessary? Yes, it links the analysis to the number of studies. Can I use '23' as a word? You can write dreiundzwanzig, but digits are better for C1 level science. Why is it 'wurde' and not 'ist'? Because it's the passive voice for a completed process. Does 'Meta' mean the same as in English? Yes, it comes from Greek meaning 'beyond' or 'about.' Is this phrase common in newspapers? Yes, very common in the science section. Can I say 'durchgeführt worden'? Yes, that is the past perfect version. Is it okay for a job interview? Yes, it makes you sound very analytical. Do I need to be C1 to use this? It is a C1 level structure, but anyone can learn it! Is there a shorter version? You could say 'Die Analyse ist fertig,' but it's much less impressive.
