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
Objective: To examine whether conditions associated with elevated-estrogenic states, including obesity, type 2 diabetes mellitus (T2DM), and postmenopausal estradiol hormone replacement therapy (HRT), are associated with the development of otosclerosis. Methods: We performed 3 retrospective cohort analyses using the US TriNetX network. Population included adults ≥18 years of age with an ear evaluation (the International Classification of Diseases [ICD]-10 Z01.1). Exposures included obesity (ICD-10 E66), T2DM (ICD-10 E11), and HRT (RxNorm 4083). Primary outcome of interest was otosclerosis (ICD-10 H80). Exclusion criteria for obesity and T2DM cohorts included type 1 diabetes (ICD-10 E10); for all cohorts, criteria included congenital ear abnormalities (ICD-10 Q16) or outcome of interest ≥20 years ago. 1:1 propensity score matching was performed on each cohort for demographics, metabolic comorbidities, ototoxic medications, lifestyle, body mass index, age, and sex. Relative risk with 95% confidence intervals was calculated; Results: Otosclerosis occurred in 25 individuals with obesity with 52 controls (risk ratio [RR] = 0.48, Conclusions: Obesity and estradiol HRT are associated with a decreased risk of developing otosclerosis. A similar but nonsignificant trend was found in patients with T2DM. This suggests a protective role of estrogen against otosclerosis. Future studies may serve to elucidate longitudinal hormone profiling and identify a therapeutic local intervention for individuals with otosclerosis.
