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

Megasporogenesis, megagametogenesis and embryogenesis of Liparis elliptica (family Orchidaceae, tribe Malaxideae, subtribe Malaxidinae) have been studied. It was shown that the L. elliptica embryo sac is monosporic and develops from the chalazal cell of the megaspore triad according to the modified Polygonum type. The embryo sacs are reduced to four-six nuclei. The suspensor is unicellular, spherical in shape, originating from the basal cell (cb). A unique feature of L. elliptica is the unitegmal ovule, which distinguishes this species from other members of the tribe Malaxideae. The seed coat is formed by an outer layer of the single internal integument. Reduction of the outer integument is a rare feature for epiphytic orchid species with photosynthetic leaves.
