Predicting individual hemoglobin abnormalities using longitudinal data in clinical practice.
Article in BMC medical informatics and decision making, 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
backgroundIn preventive medicine, the promotion of health and well-being through early detection and intervention is crucial to preventing the development of diseases. This study aims to predict potential abnormalities in hemoglobin levels before they occur, using individualised observations within normal ranges.
methodsWe utilise a dataset generated over seven years, comprising 30,000 patients. Multiple prediction models are employed to identify hemoglobin trends within individuals and predict their next-to-measure hemoglobin value based on past measurements. We focus on whether, at a specific point in time, the individual's values are likely to run outside of the individual 'normal' bounds. A Generalised Additive Model is explored as a plausible approach for predicting future individual hemoglobin values. By calculating confidence intervals for predicted hemoglobin values, we evaluate prediction uncertainty, while assessing the percentage of accurate predictions within these intervals to gauge the reliability of our model's prediction.
resultsWe find that for 88.47% of the cases, our model accurately predicts whether patients' hemoglobin levels will stay within individual 'normal' bounds or deviate from them, demonstrating its effectiveness in identifying 'out-of-normal' measurements.
conclusionsThe findings hold practical significance, potentially reducing unnecessary blood draws and preventing the onset of abnormal hemoglobin levels through preventive healthcare interventions or digital lifestyle coaching. Moreover, early detection and intervention can significantly impact individual patients by preventing disease development.
