Overexpression of ODF1 in Gastrointestinal Tract Neuroendocrine Neoplasms: a Novel Potential Immunohistochemical Biomarker for Well-differentiated Neuroendocrine Tumors.
Article in Endocrine pathology, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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.
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
Gastrointestinal tract neuroendocrine neoplasms (NENs) are a group of rare heterogeneous tumors with different prognoses. The 2019 WHO classification of digestive system tumors defines the classification of NENs as neuroendocrine tumors (NETs G1-G3) and neuroendocrine carcinomas (NECs). We investigated outer dense fiber of sperm tails 1 (ODF1) expression in 137 gastrointestinal tract NENs including 53 NETs G1, 29 NETs G2, 3 NETs G3, and 52 NECs. Twenty adenocarcinomas and 6 squamous cell carcinomas also were included in the study. The results showed that ODF1 was positive in 83 of 85 (97.6%) primary gastrointestinal tract NETs, including 9 of 10 (90%) gastric, 19 of 19 (100%) small bowel, 10 of 11 (90.9%) colorectal, and 45 of 45 (100%) appendiceal neoplasms. There was a significantly statistical difference in the rates of ODF1 positivity in NETs (83/85, 97.6%) vs NECs (25/52, 48.1%, P < 0.001). ODF1 showed diffuse staining in NETs G1 (53/53, 100%) and NETs G2 (28/29, 96.6%), > 50% staining in NETs G3 (2/3, 66.7%), and focal staining (< 50%) in NECs (23/52, 44.2%) but 2 cases (2/52) showed > 50% staining. ODF1 showed no expression in all 20 adenocarcinomas and 6 squamous cell carcinomas. In conclusion, ODF1 was firstly identified as a novel marker for NENs, especially for NETs in the gastrointestinal tract. The expression mechanism and clinical significance of ODF1 in NENs needed further study.
