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
backgroundZebrafish are widely used in various research fields and to fulfil the diverse research needs, numerous zebrafish lines are available, each with a unique domestication background, potentially resulting in intraspecies differences in specific biological functions. Few studies have compared multiple zebrafish lines under identical conditions to investigate both inter- and intra-line variability related to different functions. However, such variability could pose a challenge for the reproducibility of results in studies utilising zebrafish, particularly when the line used is not clearly specified. This study assessed growth, stress status (cortisol, serotonin) and reproductive capabilities (maturity, fecundity, fertilisation rate, sperm quality) of four commonly used wild-type zebrafish lines (AB, SJD, TU, WIK) using standardized protocols.
resultsThe stress markers levels were found to be similar across the lines, indicating that the endocrine stress status is robust to diverse domestication histories. Variations were observed in the growth and reproductive parameters. The lines exhibited differences in the timing of puberty (86 dpf for AB and SJD lines vs. 107 dpf for the WIK line) despite achieving similar sizes, suggesting that there are line-specific variations in the induction of maturation. Additionally, the AB line demonstrated higher sperm quality than did the other lines and higher fecundity and fertilization rates than did the SJD line. The AB line also exhibiting a smaller adult size but a heavier brain relative to its body weight.
conclusionThese findings emphasize the importance of line selection for zebrafish research, indicating that researchers should consider line-specific traits to ensure the biological relevance and reproducibility of the results.
