Heterozygous Eif4nif1 Stop-Gain Mice Replicate the Primary Ovarian Insufficiency Phenotype in Women.
Article in Endocrinology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
We created the c.1286C>G stop-gain mutation found in a family with primary ovarian insufficiency (POI) at age 30 years. The Eif4enif1 C57/Bl6 transgenic mouse model contained a floxed exon 10-19 cassette with a conditional knock-in cassette containing the c.1286C>G stop-gain mutation in exon 10. The hybrid offspring of CMV-Cre mice with Eif4enif1WT/flx mice were designated Eif4enif1WT/Δ for simplicity. A subset of female heterozygotes (Eif4enif1WT/Δ) had no litters. In those with litters, the final litter was earlier (5.4 ± 2.6 vs 10.5 ± 0.7 months; P = .02). Heterozygous breeding pair (Eif4enif1WT/Δ × Eif4enif1WT/Δ) litter size was 60% of WT litter size (3.9 ± 2.0 vs 6.5 ± 3.0 pups/litter; P < .001). The genotypes were 35% Eif4enif1WT/flx and 65% Eif4enif1WT/Δ, with no homozygotes. Homozygote embryos did not develop beyond the 4- to 8-cell stage. The number of follicles in ovaries from Eif4enif1WT/Δ mice was lower starting at the primordial (499 ± 290 vs 1445 ± 381) and primary follicle stage (1069 ± 346 vs 1450 ± 193) on day 10 (P < .05). The preantral follicle number was lower starting on day 21 (213 ± 86 vs 522 ± 227; P < .01). Examination of ribosome protected mRNAs demonstrated altered mRNA expression. The Eif4enif1 stop-gain mice replicate the POI phenotype in women based on an earlier end to reproduction due to oocyte loss. The unique mouse model provides a platform to study regulation of protein translation across oocyte and embryo development in mammals.
