Simplified Analysis of Native Steroid Esters in Dried Blood Spots by LC-MS
Article in Journal of mass spectrometry : JMS, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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.
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
Steroidal esters (e.g., testosterone, nandrolone and boldenone esters) belong to the substance class prohibited in professional sport that is particularly frequently abused due to its considerable performance-enhancing effects. Thus, a high number of adverse analytical findings in doping controls is reported every year. Unfortunately, the analysis of steroids that are not exclusively of exogenous nature and, in particular, their differentiation from endogenously produced steroids is very time-consuming and resource-intensive (necessitating isotope-ratio mass spectrometric analysis). The direct detection of the applied (unequivocally exogenous) steroidal esters in blood or dried blood spots (DBS) can offer a much simpler approach. In the present project, the analysis of 17 underivatized steroidal esters (composed of testosterone, nandrolone and boldenone species) is reported, employing liquid chromatography-(low-resolution)-MS
