Matrix-assisted Laser Desorption Ionization Mass Spectrometry for Detection of α/β-Chain Changes From Human Hemoglobin: An Exploratory Study.
Article in Analytical science advances, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
In this work, we developed a matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF-MS) method to directly analyze human whole blood samples. 1.0 µL of whole blood samples and 1.0 µL of optimized organic matrix were directly loaded onto the sample plates for MALDI-TOF-MS detection. A total of 59 whole blood samples were investigated in this work, including 23 healthy control samples, 28 α-globin gene triplication carriers with α-chain repetition, and eight deletional hemoglobin H disease (HbH) patients with α-chain deficiency. Human hemoglobin (Hb) chains with high signal-to-noise were directly observed. It is found that there is a change in signal ratios of α/β-chains of Hb from blood samples in thalassemia subtypes by comparing the ratios obtained from healthy blood samples.
