Stability indicating RP-HPLC method for estimation of finerenone and its related substances in new dosage form.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Stability indicating RP-HPLC method was developed and validated for the estimation of finerenone (FIN) in pure and in new tablet dosage form. The proposed approach was applied and validated for determination of (FIN) related substances. Stability studies of (FIN) was carried out using five stress conditions; acid, alkali, oxidation, photodegradation and heat degradation. The chromatographic analysis of (FIN) was based on using mobile phase consist of filtered and degassed mixture of 450mL water, 550mL acetonitrile and 10mL triethylamine with pH adjusted to 7. Phenomenex (C18, 4.6 × 250 mm, 5 μm) column was used with 0.8 mL/min flow rate and 40 °C column temperature. The UV detection was set at 252 nm with injection volume (10µL). The (FIN) retention time was 4.437 ± 0.05 min. The proposed technique was validated according to ICH guidelines with good linearity in ranges (8-30 µg/mL) for assay of (FIN) and (0.2-1.4 µg/mL) for determination of (FIN) unspecified impurities. The found mean percentage recoveries were 99.74% for (FIN) assay and 99.11% for (FIN) related substance determination which indicate good trueness. The developed approach was successfully applied for the determination of (FIN) in Nexifinerenone
