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

Life on earth is governed by light, chemical reactions, and the second law of thermodynamics, which defines the tendency for increasing entropy as an expression of disorder or randomness. Life is an expression of increasing order, and a constant influx of energy and loss of entropic wastes are required to maintain or increase order in living organisms. Most of the energy for life comes from sunlight and, thus, photosynthesis underlies the survival of all life forms. Oxygenic photosynthesis determines not only the global amount of enthalpy in living systems, but also the composition of the Earth's atmosphere and surface. Photosynthesis was established on the Earth more than 3.5 billion years ago. The primordial reaction center has been suggested to comprise a homodimeric unit resembling the core complex of the current reaction centers in Chlorobi, Heliobacteria, and Acidobacteria. Here, an evolutionary scenario based on the known structures of the current reaction centers is proposed.
