[Replicative and biochemical ageing mechanisms among females with Turner syndromes].
Article in Problemy endokrinologii, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
background2025 is going to be the 100th anniversary of the first historical description of Turner syndrome - complex of genomic abnormalities, congenital gonadal disruption and hypergonadotropic hypogonadism. Total estrogenic deficiency triggers development of age-related comorbidities. There is no doubt that personalized search for replicative markers of cellular aging among females with Turner syndrome is needed.
aimTo evaluate features of replicative (telomere length) and biochemical (lipid profile, calcium-phosphate album, thyroid hormones, markers cytolysis and cholestasis, carbohydrate metabolism, nitrogenic metabolism, electrolytes, FSH) markers among females with Turner syndrome. MATERIALS AND
methodsResearch has been provided in collaboration between Endocrinology Research Centre of the Russian Ministry of Health and Lomonosov Moscow State University Medical Research and Educational Centre in the period since 10.01.2021 until 01.08.2022. Females with non-iatrogenic hypergonadotropic hypogonadism caused by Turner syndrome (45,X0; 45,X/46,XX; 45,X/46,X,r(X); 13-40 y.o.; n=26) and primary ovarian insufficiency (18-39 нyears=26); healthy females of reproductive age (15-49 y.o.; n=24). Patients have undergone laboratory genetic (leucocyte telomere length), biochemical (fasting glycaemia, urea, creatinine, common/conjugated bilirubin, ALT, AST, gamma-glutamyl transferase, triglycerides, HDL-P, LDL-P, common cholesterol, common/ionized calcium, phosphate, vitamin D, sodium/potassium/chlorides, FSH, HbA1c) analyses. Body measurements - body mass, body height. DNA extraction - provided with Qiagen DNA blood mini kit (Germany). Leukocyte telomere length - with real-time polymerase chain reaction PCR (Flow-fish). Soft program IBM SPSS Statistics (version 26,0 for Windows).
results1. Females with Turner syndrome have significantly lower mean telomere length (8,22 kB [6,63-9,30]) than with primary ovarian insufficiency (10, 34 кБ [8,41-13,08], p<0,001) and healthy reproductive age females (10,77 kB [9,95-13,16], р>0,05).2. Telomere length correlates directly and significantly with longevity of menopausal hormonal therapy among females with primary ovarian insufficiency (ρ = 505; p<0,001).3. Patients with Turner syndrome are inclined to vitamin D deficiency (р<0,001), dyslipidemia (р=0,01); increase of levels of aminotransferases, cholestasis markers, phosphate and FSH (р<0,001).
conclusionTurner syndrome is serious genetic disease that leads not only to infertility but to significant decrease of quality/life longevity out of "healthy aging" conception.
