Response to "Caution: Fundamental data quality issues underlying intelligent prediction of enzyme optimal pH".
Article in Briefings in bioinformatics, 2026. 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
We respond to concerns regarding fundamental data quality issues in datasets used for machine learning prediction of enzyme optimal pH (pHopt). We re-examined six questioned protein entries by tracing their annotated pH values to the original literature. Our analysis confirmed substantial discrepancies for several entries, including incorrect experimental values, misassigned protein identities, and proteins lacking the reported catalytic activity, whereas one entry was consistent with the literature. These findings support the need for rigorous verification of biochemical data underlying predictive models. We emphasize that careful literature based curation is essential for improving dataset reliability and model validity, and future iterations of pHopt predictors will be developed using more rigorously validated datasets.
