Association between salivary and blood hormone concentrations using an automated electrochemiluminescence immunoassay technique: Challenges and pitfalls.
Article in Experimental physiology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Blood-based measures are considered the gold standard for evaluating steroid hormone concentrations, particularly for confirmation of hormone profiles in female-specific research. However, saliva sampling offers several advantages: it can be collected independently by participants, is less invasive and might be a more time- and cost-effective solution. This preliminary study explored associations between salivary and blood plasma hormone (oestrogen, progesterone and cortisol) concentrations using an automated electrochemiluminescence immunoassay technique. Eight healthy, physically active females with a regular natural menstrual cycle provided: (1) daily app-based menstrual tracking data; (2) daily saliva samples; and (3) two blood samples, each at different time points in the third to fifth menstrual cycle estimated using the backward calculation method. Associations between saliva and blood hormone concentrations were analysed using repeated-measures correlations. Progesterone and oestrogen showed positive associations between blood plasma and salivary measures; (r
