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
Chronic pain (CP) is a public health problem with significant consequences for the patient's life. This study aims to analyze the prevalence of sick leave due to CP in Spain and to explore how pain intensity and mental disorders mediate the relationship between sick leave and health-related quality of life (HRQL) in subjects with CP. This study is a secondary analysis from data collected in a cross-sectional study called "Barometro del Dolor" with 7058 participants, representing the Spanish adult population. Sociodemographic information, presence and characteristics of CP, sick leave due to CP, anxiety and depression (HADS) and HRQL (SF-12v2) were collected. The prevalence of sick leave and four serial multiple mediation analyses were conducted. CP prevalence was 25.9% (95%CI 24.8-26.9), while 28.6% (95%CI 26.4-30.8) needed sick leave due to CP in the last year. Sick leave was associated with worse HRQL through the mediating effect of pain intensity and anxiety/depression, showing a non-significant direct effect for the mental component summary of the SF12v2 after accounting for the indirect effects. The direct effects linked CP sick leave to a worse physical component summary, higher pain intensity, anxiety and depression. This study highlights the strong impact of CP on the Spanish workforce providing new insights into hypothesized statistical pathways linking CP sick leave and HRQL through pain intensity and anxiety/depression symptoms.
