Estimated cumulative rates of dissertation publication over time.

<p>Overall estimates and 95% confidence intervals (left panel) are derived from the weighted Cox regression model (see <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0192219#pone.0192219.t003" target="_blank">Table 3</a>). Subfield estimates (right panel) are derived from the unweighted Kaplan-Meier regression model. In both plots, cumulative publication estimate = one minus survival function.</p

Flow diagram reflecting the numbers of dissertations included at each stage of the sampling process.

<p>Note. PQDT = ProQuest Dissertations and Theses. ^a Categories of excluded dissertations are mutually exclusive, summing to 100%. ^b PQDT exclusion criteria were applied sequentially in the order presented; thus, the number associated with each exclusion criterion reflects how many were excluded from the sample that remained after the previous criterion was applied. Adapted from the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) flow diagram [<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0192219#pone.0192219.ref027" target="_blank">27</a>].</p
