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

backgroundUrinary incontinence is a common urinary tract disorder that has gradually become a significant health issue affecting middle-aged and elderly women worldwide in recent years. This study aimed to investigate the relationship between insulin resistance (IR) and female urge urinary incontinence (UUI).

methodThis study enrolled individuals aged 20 and older to investigate the relationship between IR and female UUI. The analysis leveraged data from the National Health and Nutrition Examination Survey (NHANES) from 2005 to 2016. We employed multiple logistic regression models to assess the relationship between IR and female UUI. In addition, subgroup analyses, interaction tests, and smooth curve fitting were performed to evaluate the stability of this association.

resultThis study included a total of 2,961 participants, with a UUI prevalence rate of 28.20%. After adjusting for confounding variables, a positive correlation was found between the Homeostatic Model Assessment of Insulin Resistance (HOMA-IR) and the prevalence of UUI (Model Ⅲ OR = 1.03,95% CI: 1.00, 1.06, P = 0.0264). Smoothed curve fitting also demonstrated a significant positive linear correlation between HOMA-IR and the risk of UUI in women. Subgroup analysis revealed that the association between HOMA-IR and UUI remained consistent across all subgroups, and no subgroup showed an interaction effect on this association (P for interaction > 0.05). However, when body mass index (BMI) was further added to the fully adjusted model, the association between HOMA-IR and the prevalence of UUI was substantially attenuated. It was no longer statistically significant (Model IV OR = 1.01, 95% CI: 0.98, 1.04, P = 0.4243). In model IV-based smooth curve fitting and subgroup analysis, the association between IR and UUI was weakened and not statistically significant.

conclusionIn non-diabetic women, obesity is the primary modifiable risk factor for UUI. It is crucial to prioritize weight management and obesity prevention as core strategies for reducing the risk of UI in this population. Although IR remains an important indicator of metabolic dysfunction, interventions targeting UI should focus on comprehensive weight control rather than directly addressing IR.
