Summary statistics for continuous variables included in our regression analysis, including the characteristic, median, and interquartile range (IQR) for bioRxiv-deposited and control groups, median, and IQR for paired differences, and p-values for Wilcoxon signed-rank test (paired, two-sided)

Characteristic	Median bioRxiv-deposited (IQR)	Median control (IQR)	Median paired difference (IQR)	p
Journal impact factor	4.53 (3.32–7.08)	4.53 (3.32–7.08)	N/A^a	N/A^a
Author count	5 (3–8)	6 (4–9)	−1 (–4–2)	< 2.2 × 10⁻¹⁶ (Z = −10.472)
First author academic age	5 (2–9)	5 (2–9)	0 (–5–4.75)	0.192 (Z = −1.305)
Last author academic age	17 (12–20)	19 (13–21)	0 (–5–3)	9.8 × 10⁻¹⁶ (Z = −8.029)

Characteristic	Median bioRxiv-deposited (IQR)	Median control (IQR)	Median paired difference (IQR)	p
Journal impact factor	4.53 (3.32–7.08)	4.53 (3.32–7.08)	N/A^a	N/A^a
Author count	5 (3–8)	6 (4–9)	−1 (–4–2)	< 2.2 × 10⁻¹⁶ (Z = −10.472)
First author academic age	5 (2–9)	5 (2–9)	0 (–5–4.75)	0.192 (Z = −1.305)
Last author academic age	17 (12–20)	19 (13–21)	0 (–5–3)	9.8 × 10⁻¹⁶ (Z = −8.029)

Groups are matched with respect to journals and thus no different in IF between groups is observed.

Note: 2 × 10^–16 represents the lower bound of p-values reported by R.
