From: A meta-review demonstrates improved reporting quality of qualitative reviews following the publication of COREQ- and ENTREQ-checklists, regardless of modest uptake

Trends for the three domains of the COREQ (domain 1: research team and reflexivity; domain 2: study design and domain 3: data analysis and reporting), plotted over time, with a smoothed LOESS curve and 95% confidence interval (light blue). Y-axis differs per domain, as the number of signalling questions per domain is different (ranges per domain: 0–8 for domain 1, 0–15 for domain 2, and 0–9 for domain 3). For clarity, data points are jittered on the y-axis, by adding a Gaussian error with a standard deviation of 0.1
