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

Haematococcus pluvialis is mainly known by its high astaxanthin content. This carotenoid, with strong antioxidant properties, is naturally accumulated in microalgal cells under stressful conditions (light intensity variation, nutrient deprivation, osmotic stress, etc.). Nevertheless, the cost-effectiveness of such methods at a large scale is controversial, in addition to their negative impact on cell growth. We examined the effectiveness of major nutrients (nitrogen, phosphorus, copper, and iron) modification in the culture medium as well as light intensity. This study is the first to report continuous monitoring of the red stage over a 60-day culture period on final astaxanthin yield, through both biomass change and pigment accumulation. Reduced light intensity prolonged the green growth stage, while elevated light intensity (150 µmol m
