1 · What the graph read from it

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.

2 · The registry

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

Brain-derived neurotrophic factor (BDNF) and its isoforms (pro- and mBDNF) are promising neurobiomarkers. While total serum BDNF levels have been previously validated, the newer isoforms have not. We aimed to identify the most common serum pro- and mBDNF assays through a literature search (MEDLINE/PubMed, until March 2024), and to compare their methodological performance in 23 human serum samples [total BDNF: R&D Systems, #DBNT00; both isoforms: R&DSystems (#DY3175, #DBD00); Aviscera-Bioscience (#SK00752-09, #SK00752-01); FineTest (#EH4255, #EH0043)]. Western-blot and cross-reactivity assays were used to confirm whether the kits tested for the declared isoforms. The total BDNF (#DBNT00) and pro-BDNF (#DY3175) ELISA kits from R&D Systems, and the pro-BDNF ELISA kits from FineTest (#EH4255) and Aviscera-Bioscience (#SK00752-01) showed high specificity, sensitivity, accuracy, and reproducibility. None of the commercial brands tested for mBDNF quantification showed optimal specificity, although R&D Systems (#DBD00) showed an acceptable result. Additionally, comparison of serum mBDNF levels by direct measurement and estimation (total minus pro-BDNF) using the three R&D Systems kits in the 23 serum samples showed acceptable variation (± 15%). This work indicated that there is a need to continue improving the specificity of some ELISA kits, mainly those measuring mBDNF. Total, pro- and m-BDNF serum levels can be quantified using the R&D Systems kits, whereas pro-BDNF serum levels could, in principle, be measured using any of the three brands evaluated.
