Reporting quality by article formatting. a Overall reporting score by embedding of figures in all preprints assessed. Preprints assessed in both stages of the study were included only once for this analysis, with the mean of reporting scores from both assessments. Mean ± S.D.: Non-embedded = 64.6 ± 10.9, n = 59; Embedded = 70.8 ± 11.6, n = 26. 95% C.I. [1.0, 11.4]. Student’s t-test: t = 2.37, p = 0.02. b Difference between scores from peer-reviewed to preprint version by embedding of figures in the preprint version (paired sample). Mean ± S.D.: Non-embedded = 4.3 ± 8.3, n = 38; Embedded = 5.6 ± 9.0, n = 18. 95% C.I. [− 3.6, 6.1]. Student’s t-test, t = 0.55, p = 0.58
