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

We found filamentous structures resembling conchocelis of red algae within the nacreous layer of the Akoya pearl oyster Pinctada fucata shell. Microscopic analyses revealed that these filamentous structures had an autofluorescence and varied in length, occasionally branched, and exhibited diameters ranging from 2 to 5 μm-consistent with previously reported sizes for Bangiales conchocelis. We extracted DNA from organic matrix sheets obtained by decalcifying the shell and performed PCR with primers targeting red algae from the family Bangiales to identify these structures. Sequencing analysis confirmed a 94% match with that of Bangia fuscopurpurea, establishing the presence of Bangia conchocelis within the shell. Conchocelis distributed predominantly near the anterior ear across all examined shells. In 3-year-old oysters, conchocelis filament densities reached approximately 250 filaments per 1 mm
