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

The International Classification of Diseases (ICD) system plays a key role in health data classification but currently lacks a specific code for refractory chronic cough (RCC). This study analyzed ICD-10 coding patterns among 331 RCC patients enrolled in the Korean Chronic Cough Registry. Each patient had a median of 3 [IQR: 2-4] ICD-10 codes at their most recent outpatient visit. The most frequently assigned primary code was R05 (Cough), recorded in 80.4% of cases. Patients with R05 as their primary code tended to have fewer identifiable etiologies but reported more cough hypersensitivity symptoms. Additionally, the number of ICD-10 codes correlated with both cough severity and cough-specific quality-of-life impairment. In a pooled analysis including RCC and non-RCC cases, the R05 code showed high specificity (80.5%) but low sensitivity (25.8%) for RCC. These findings support the need for a dedicated ICD code to accurately capture RCC in clinical and epidemiological contexts.
