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

The gastric endocrine population comprises functionally distinct cell types that exhibit both neuronal and endocrine characteristics; however, their molecular markers remain incompletely defined. Here, we identify growth differentiation factor 9 (GDF9), nephrin (NPHS1), and rearranged during transfection (RET) as novel markers of gastric endocrine cells. A co-immunofluorescence (IF) analysis demonstrated that GDF9, NPHS1, and RET are co-expressed with chromogranin A (CHGA), a well-known marker of gastrointestinal endocrine cells. Further Co-IF analysis revealed that GDF9-expressing cells were negative for ghrelin and somatostatin, whereas NPHS1 was co-expressed with both hormones. A subpopulation of RET-positive cells co-expressed ghrelin but not somatostatin. Notably, GDF9- and RET-positive cells co-expressed dopamine decarboxylase (DDC), consistent with enrichment in enterochromaffin-like (ECL) cells. Revisitation of our previous mRNA-sequencing data revealed reduced transcript levels of
