In Vitro α/β Ratio Variations in Cervical Cancer, with Consequent Effects on Equivalent Dose in 2 Gy Fraction in High-Dose-Rate Brachytherapy.
Article in Advances in radiation oncology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Purpose: To determine the distributions of published α/β values measured in vitro and the resulting uncertainties in the equivalent dose in 2 Gy fractions (EQD Methods and Materials: An analysis of 98 published α/β values from 31 papers was conducted, spanning 23 cervical cancer cell lines. Values were further divided into squamous cell carcinoma and adenocarcinoma histologies. Probability distributions were fit to histograms using the bootstrapped Kolmogorov-Smirnov goodness-of-fit test. Both average and most probable α/β values for cervical cancer were determined. The probability distributions were then applied to three representative external beam therapy (EBT) plus HDR brachytherapy prescriptions to determine the potential impact they would have on the equivalent dose in 2 Gy fractions (EQD Results: Published results of α/β values ranged from 1.06 to 34.3 Gy. A right-skewed log-normal distribution was shown to be the best fit for overall α/β values as well as for squamous cell carcinoma and adenocarcinoma subtypes.. Average α/β values were determined to be 8.05, 8.47, and 6.60 Gy for the total, squamous cell carcinoma, and adenocarcinoma groups, respectively. The most probable values were 4.25, 4.34, and 4.22 Gy, respectively. The variations in α/β values led to uncertainties of -8.0 to 46.4 Gy in EQD Conclusion: There was large variation in
