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

In the context of global biodiversity decline, the monitoring and assessment of marine biodiversity have gained increasing importance. Thaliacea, a group of filter-feeding gelatinous zooplankton, play crucial roles in the carbon cycle and pelagic food webs, yet their diversity remains poorly documented due to challenges in sampling and identification. This knowledge gap is particularly evident in the South China Sea, a highly dynamic subtropical marginal sea. To achieve a comprehensive assessment of thaliacean diversity in the South China Sea, we conducted two cruises in the western South China Sea during the summers of 2020 and 2022. A total of 28 thaliacean species were recorded, representing the highest species richness ever reported from a single study in the South China Sea. Among these, five species are newly recorded, all belonging to the family Doliolidae (order Doliolida):
