Questions and Answers
Why are two values shown for the efficacy of each treatment (a lower and a higher one)?
Since there is more than one scientific article studying the efficacy of each treatment, we included in the table both the lowest efficacy value found in the research related to that treatment and also the highest, so you can get an idea of this variation. The efficacy of each treatment in different studies may vary depending on the dosage used in the study, its duration, the characteristics of the population that received the treatment, and other factors.
Where do the efficacy data on the Telix website come from, and how are they calculated?
The efficacy data presented are extracted from studies specifically selected on treatments for migraine and chronic headache. The efficacy data we use at Telix are the simple absolute efficacy values of each treatment, taking into account the benefit obtained with the treatment. In other words, from each study we select the number of people who achieved a specific benefit with the treatment (cure, elimination of symptoms, reduction of symptoms, or prevention) and divide this number by the total number of people who started the treatment, thus obtaining the efficacy percentage.
Each study has a date, and there are several studies per treatment. Why is only one date shown on the treatment list page?
On the list on this page, we always use the date of the most recent study found for a given treatment.
How many studies are included per medication?
We include all studies on treatment efficacy that we are able to find, but there are several research databases in different languages. If you have seen any relevant study on a treatment that has not yet been indexed on our platform, please send it to us! :)
Why does the efficacy percentage include labels such as cure, elimination of symptoms, reduction of symptoms, or prevention?
To explain the criterion used in calculating efficacy. For example, if it says “cure,” it means we used the number of people who achieved complete remission of the disease after using the treatment. In the case of “elimination of symptoms,” it means we used the number of people whose symptoms were 100% eliminated at that time with the treatment, and so on.
Why isn’t the efficacy percentage shown in the full text of each study’s external link the same as the one presented on the Telix website for that study?
Because most studies present relative efficacy data (comparing the treatment with placebo or with other treatments), while at Telix we present simple absolute efficacy data. This was the way we found to make it possible to compare different treatments, from different specialties, conducted in different studies, locations, dates, and with distinct criteria. The data we extract from each study are only the following: how many participants benefited from the treatment, what types of benefits were achieved (cure, elimination of symptoms, reduction of symptoms, or prevention), and how many participants started that specific treatment. Based on this, the efficacy percentage presented on Telix is calculated.
Why doesn’t the website address the causes of migraine and chronic headache?
Migraine is a multifactorial condition, which means it can have different causes. On our website, we do not detail the causes of the disease, as our focus is on providing information about treatments for migraine and chronic headache, so that users can find this information in a simple and clearly understandable way.
Why doesn’t the website address f migraine and chronic headache?
We do not address what migraine is, since the platform’s focus is exclusively on treatment options for migraine and chronic headache. Our website is designed for people who already live with migraine or chronic headache and are only looking for information about treatments.
