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

backgroundSymptoms suggestive of uncomplicated cystitis constitutes one of the most common reasons to seek health care in otherwise healthy women. Previous studies regarding the relationship between sociodemographic factors and uncomplicated cystitis are limited, mainly because of the lack of nationwide population-based data from primary healthcare settings, where most uncomplicated cystitis are diagnosed.

methodsA Swedish nation-wide open cohort study consisting of 2 044 065 females who were 15-50 years of age during the study period (1997-2018) was conducted. The outcome was first event uncomplicated cystitis diagnosed in primary health care rather than an assessment of the "true" incidence, which is not feasible in nationwide datasets. Cox regression models were used in the statistical analyses.

findingsThe study identified 546 076 first events of uncomplicated cystitis (26•7% of the study population), corresponding to an incidence rate per 100 person-years of 2•91 (95% CI 2•90-2•91). In fully adjusted models, rural living was associated with lower risks of uncomplicated cystitis (Hazard ratio, HR, 0•67; 95% CI, 0•66-0•68) compared to urban living, while both Middle Eastern/North African (HR, 1•15; 95% CI, 1•14-1•16) and Latin American/Caribbean (HR, 1•24; 95% CI, 1•22-1•27) women had higher risks compared to Swedish women. Low education and low income were also associated with higher risks compared to high education and high income.

interpretationThis study presents novel risk factors associated with uncomplicated cystitis in women. The findings may help health care workers in the treatment of women with symptoms of uncomplicated cystitis.
