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

The phenomenon of grade inflation has been studied extensively at high school and undergraduate levels, yet little is known about its occurrence in graduate education. This study bridges this gap by examining graduate grade inflation using data from one U.S. research intensive university, covering two decades of admissions across 75 master's programs (N = 24,815) and 78 doctoral programs (N = 15,701). Relying on both linear and ordinal multilevel models, we investigated the presence of grade inflation and potential variations by degree level and individual academic programs at the program level. Our findings provide preliminary evidence for the presence of graduate grade inflation and suggest that the magnitudes differ across individual academic programs. There is also evidence showing that the trend of grade inflation significantly differed across master's and doctoral programs. This apparent inflation undermines the signaling value of grades for employers and admission decisions in the labor market and academic selection, as well as for research, feedback, and learning purposes. Future research should replicate our findings using multi-institutional samples and examine drivers of graduate grade inflation to more accurately estimate its magnitude.
