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
introductionInvasive pulmonary aspergillosis (IPA) in hematological malignancy populations has high mortality rates. While there are identified prognostic factors for mortality, conflicting results are reported from the studies including bronchoalveolar lavage galactomannan (GM) measurements and co-infections. We aimed to evaluate risk factors associated with in-hospital mortality in a hematological malignancy population undergoing bronchoscopy with a preliminary diagnosis of IPA in a single tertiary care center.
methodPatients undergoing bronchoscopy with a preliminary diagnosis of IPA were included in this retrospective study. Bacterial co-infection was defined as a positive bacterial culture in respiratory samples within ± 7 days of the index bronchoscopy procedure.
resultsStudy population consisted 305 patients diagnosed as possible, probable or proven IPA. 57 patients presented with fungal and bacterial co-infection. In-hospital mortality was observed in 98 (33.6%) patients. Patients with mortality status were older and were not in remission for hematological malignancy. Serum GM, bronchoalveolar lavage (BAL) GM and bronchial lavage (BL) GM levels showed a significant relation with in-hospital mortality but weak accuracy. In multivariate analysis for risk factors of in-hospital mortality; age, remission status, number of nodules in HRCT and having fungal infections with or without combined bacterial infection were independent risk factors.
conclusionCo-infections in this susceptible population should not be overlooked even in the presence of fungal infection evidence. BAL and BL GM tended to have a stronger relation with survival than serum GM measurements taken at the same time. The number of nodules in radiological assessment might be an indicator of mortality. Radiological changes through the disease course might be assessed in further studies.
