Nitrogen deprivation results in photosynthetic hydrogen production in Chlamydomonas reinhardtii.

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
The unicellular green alga Chlamydomonas reinhardtii is able to use photosynthetically provided electrons for the production of molecular hydrogen by an [FeFe]-hydrogenase HYD1 accepting electrons from ferredoxin PetF. Despite the severe sensitivity of HYD1 towards oxygen, a sustained and relatively high photosynthetic hydrogen evolution capacity is established in C. reinhardtii cultures when deprived of sulfur. One of the major electron sources for proton reduction under this condition is the oxidation of starch and subsequent non-photochemical transfer of electrons to the plastoquinone pool. Here we report on the induction of photosynthetic hydrogen production by Chlamydomonas upon nitrogen starvation, a nutritional condition known to trigger the accumulation of large deposits of starch and lipids in the green alga. Photochemistry of photosystem II initially remained on a higher level in nitrogen-starved cells, resulting in a 2-day delay of the onset of hydrogen production compared with sulfur-deprived cells. Furthermore, though nitrogen-depleted cells accumulated large amounts of starch, both hydrogen yields and the extent of starch degradation were significantly lower than upon sulfur deficiency. Starch breakdown rates in nitrogen or sulfur-starved cultures transferred to darkness were comparable in both nutritional conditions. Methyl viologen treatment of illuminated cells significantly enhanced the efficiency of photosystem II photochemistry in sulfur-depleted cells, but had a minor effect on nitrogen-starved algae. Both the degradation of the cytochrome b₆ f complex which occurs in C. reinhardtii upon nitrogen starvation and lower ferredoxin amounts might create a bottleneck impeding the conversion of carbohydrate reserves into hydrogen evolution.
