1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

backgroundThe cross-sectional study aimed to compare and evaluate the conversion rates of theses and dissertations of Ph.D. and specialization programs of the periodontology department in Türkiye.

methodsA total of 789 theses of dentists who successfully graduated from higher education institutions in Türkiye between 2001 and 2020 and qualified to become specialist dentists were analyzed. In these analyses, after descriptive information, the status of the theses converted into publications, the duration of publication, the number of citations, the indexes of the journals, and the employment status of dentists in the academy after graduation were evaluated. The Shapiro-Wilks test and Kolmogorov-Smirnov test were applied for the normality test. A chi-square test was used for categorical variables. Independent T-test, Mann-Whitney U test, Kruskal-Wallis test, and time series linear regression test were applied.

results336 Ph.D. (60.54%) and 110 (47%) dentists in specialty programs had their theses translated for publication (p = 0.001). 242 Ph.D. dentists (72.02%) published their thesis in an SCI-Expanded journal, while only sixty-nine specialty dentists (62.7%) published in these journals (p = 0.001). The publications of dentists with Ph.D. in SCI-Expanded indexed journals were mostly in journals ranked Q1 and Q2, while those of dentists with specialization were in journals ranked Q3 and Q4 (p = 0.012). The publications of dentists with Ph.D. received an average of 24 citations on the Web of Science, while those of specialists received seven (p = 0.001).

conclusionsThe decline in the conversion of the theses of dentists graduating from the specialty program into publications may impact the field of periodontology in Türkiye. More comprehensive studies are needed to evaluate the effectiveness of the specialty program.
