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

Habilitation is a procedure by which one of the highest university degrees is achieved in the field of medicine in Germany. We hypothesize that this academic milestone represents an incentive for scientific productivity that drops off once a scientist has reached this career steep. This study aims to compare scientific performance of German scientists before and after completing this milestone with special focus on orthopedic surgeons and traumatologists (O&T).Scientists who had completed their habilitation in human medicine were researched from public announcements in the period Jan-Dec 2018. The periods Jan 2016 to Dec 2018 and Jan 2020 to Dec 2022 were defined as pre- and post-habilitation phases, respectively. Scientific performance was calculated using normalized citation percentiles (NCPs) from author records in Web of Science. Association between sex, subject area, and change in performance were analyzed.NCP values of 742 scientists were analyzed showing a significant decrease after completing habilitation (
