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

Background: Nutritional status has been increasingly recognized as an important determinant of outcomes in nontuberculous mycobacterial pulmonary disease (NTM-PD), but its predictive value for sputum culture conversion remains unclear. Methods: This retrospective cohort study included 416 patients with NTM-PD between January 2016 and September 2024. Patients were categorized based on nutritional status and sputum culture conversion. Logistic regression was used to identify independent predictors, and a combined predictive model was evaluated using ROC curves. Kaplan-Meier analysis assessed time to culture conversion. Internal validation was performed using bootstrap resampling. Results: Among 416 patients, 109 (26.2%) achieved sputum culture conversion. Malnourished patients had significantly lower conversion rates. Multivariable analysis showed age (OR=1.048, 95% CI: 1.012-1.085), BMI (OR=0.746, 95% CI: 0.668-0.835), hemoglobin (OR=0.936, 95% CI: 0.906-0.967), and total protein (OR=0.920, 95% CI: 0.853-0.992) were independent predictors. The combined model demonstrated strong predictive performance (AUC=0.925, sensitivity=89.3%, specificity=78.0%). Conclusion: Nutritional status is significantly associated with sputum culture conversion in NTM-PD. A combined model incorporating nutritional indicators may assist in risk stratification, although further validation is required.
