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

backgroundNontuberculous mycobacterial pulmonary disease (NTM-PD) is a chronic, debilitating infection that predominantly affects patients with a low body mass index (BMI) and leads to progressive destruction of lung parenchyma. Although pneumonia is a common cause of death among patients with NTM-PD, information on its prognosis is scarce. We evaluated the association between BMI and outcomes in patients with NTM-PD who were hospitalized for community-acquired pneumonia (CAP).

methodsUsing the Japanese Diagnosis Procedure Combination database, we identified patients with NTM-PD hospitalized for CAP between April 1, 2012, and March 31, 2020, prior to the coronavirus disease 2019 epidemic in Japan. We evaluated in-hospital mortality as the primary outcome, and length of hospital stay and readmission due to CAP within 1 year as secondary outcomes. Restricted cubic spline regression models were used to evaluate the impact of BMI as a continuous variable on the study outcomes, adjusting for potential confounders.

resultsWe included 13,302 patients (median age: 79 years [interquartile range {IQR} 72-85]; women: 63.7%; median BMI: 17.6 kg/m

conclusionsThese findings indicate that assessing BMI may play a critical role in stratifying risk and optimizing management of CAP in patients with NTM-PD.
