Incidence and prognostic factors for pulmonary infection complications in elderly patients with acute myeloid leukemia.
Article in American journal of translational research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectiveTo investigate the incidence, risk factors, and prognostic effect of pulmonary infections in elderly patients with acute myeloid leukemia (AML), and to provide evidence for optimizing infection prevention and management as well as individualized treatment strategies.
methodsWe retrospectively analyzed clinical data from 150 elderly AML patients diagnosed and treated at our hospital between March 2020 and October 2022. Their demographics, laboratory test results, treatment regimens, and follow-up records were collected and analyzed. Logistic regression was used to identify risk factors for pulmonary infections, while Kaplan-Meier survival analysis and Cox regression were employed to assess the effect of infections on survival. Time-dependent ROC curves were applied to evaluate the predictive performance of key laboratory indicators.
resultsAmong the 150 cases, the incidence of pulmonary infections was 42%. Logistic regression identified low hemoglobin (Hb < 110.5 g/L), elevated C-reactive protein (CRP ≥ 24.01 mg/L), elevated procalcitonin (PCT ≥ 0.255 ng/mL), low neutrophil count (NC < 0.475×10
conclusionPulmonary infections are common among elderly AML patients and significantly worsen their prognosis. Low Hb, high CRP and PCT, and low NC and PLT are critical risk factors for infection. Strengthening infection monitoring and initiating early intervention may improve patient survival outcomes.
