Method Meta-analysis

Clinical trial results are being pooled and re-analysed to find out which treatments actually work, and for whom. This matters because doctors and policymakers rely on systematic reviews and meta-analyses to decide which drugs to prescribe or which treatments to fund. But the statistical methods behind these reviews are often outdated or too crude to detect whether a treatment works better for certain patient groups—older people, women, or those with other health conditions. Without better methods, patients may receive treatments that are less effective for them, or effective treatments may be wrongly dismissed. The researchers are developing new statistical techniques for all types of meta-analysis, including network meta-analysis, which compares multiple treatments at once. They are also collecting more detailed patient-level data to explore why some people respond differently. To make these methods usable, they are writing open-source software, producing guidance documents, and running training courses. If successful, this work will not change daily life directly. Instead, it will quietly improve the infrastructure of medical decision-making—making clinical guidelines more reliable, drug approvals more precise, and treatment recommendations more tailored to individual patients.
