Fig. 4.

Lead lag (days) per publications date (year) in 4,762 articles of 10 Korean medical journals. Panels are rearranged by order of median value of lead lag per journal. Varying width of the violin indicates kernel density estimates. Light blue violins indicate journals that sport 2013 track record below 100 days (The ANN LAB MED is coerced into the blue group) and red ones over 100 days. Blue lines and gray shadow indicate loess smooth fit and associated standard error. Property of blue lines (solid or broken) indicates increasing or decreasing pattern. In a boxplot, boxes indicate Q1 and Q3 with dots in the box, Q2. Whiskers extend to the highest (lowest) value that is within 1.5 times interquartile range of the hinge. Note that the ordinate of each panel has a different range.
