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 Flotow has gained growing interest last years due to its high content of astaxanthin. The quick expansion of its culture worldwide has been accompanied with report of several cases of fungal contamination, mainly with chytrids, causing serious losses in astaxanthin production. Although chemical fungicides efficiently eliminate chytrids contamination, they also affect algal growth. The aim of this study was to test the efficiency of chytrids' contamination treatments without affecting algal cells. For this, agricultural fungicides (hexaconazole and copper oxychloride) have been tested at several concentrations and compared with a green decontamination strategy using calcium chloride biomineralization. Hexaconazole caused microalgae bleaching and chytrids bursting even at the lowest tested concentrations (0.01 ppm). At high concentrations, copper-oxychloride, was toxic for H. pluvialis cells, while the chytrids remained resistant to all concentrations of this fungicide. The cell number increased from 1 × 10
