Intra- and inter-plant variability of quinolizidine alkaloids in narrow-leaf lupin seeds, grown under different day/night cycles.
Article in Heliyon, 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
Inconsistent fluctuation of quinolizidine alkaloid (QA) content in lupin seeds is often observed, sometimes surpassing safe thresholds (>200 mg/kg) yet lacks a clear explanation. This study aimed to investigate the intra-plant variability of QA content in three narrow-leaf lupin genotypes: Tanjil, Quillinock, and P22660 using LC-MS/MS. QA levels in seeds from the same pods showed <30 % variation, while those from different pods in the same plant sometimes surpassed inter-plant variations (up to 94 %). The average measured QA concentrations under speed breeding conditions in Quillinock, Tanjil, and P22660 were 36, 103, and 27,000 mg/kg, respectively. The impact of longer daylight hours (16h day/8h night), a practice used in speed breeding, on QA content in the cultivar Tanjil was also studied. Longer daylight hours yielded elevated QA levels in Tanjil seeds (103 mg/kg) compared to those grown in a greenhouse (10-13h daylight, 32 mg/kg).
