Risk factors for postoperative pneumonia in patients with posterior fossa meningioma after microsurgery.
Article in Heliyon, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 1 of them a synthesis that pooled 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.
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
objectivesPostoperative pneumonia (POP) is one of the common complications associated with mortality and morbidity. Even so, it has received little intensive research after microsurgical removal for posterior fossa meningioma (PFM). In this study, we aimed to identify perioperative factors for POP after PFM microsurgery to risk-stratify patients and improve clinical outcomes. PATIENTS AND
methodsWe retrospectively review on all patients who underwent microsurgical resection (n = 321) for PFM from January 2016 to December 2018. To identify the risk factors for POP, we performed univariate and multivariate analyses successively.
results44 (13.7%) patients were diagnosed as POP. In accordance with univariate analysis, postoperative Glasgow Coma Scale (GCS) score (<13; p < 0.001), tumor size (≥3cm; p < 0.001), procedure duration (≥3 h; p < 0.001), tumor located in anterior or lateral of brainstem (p < 0.001), estimated blood loss (EBL; > 1000ml; p = 0.001) and brainstem shift (p < 0.001) were associated with POP. By multivariate analysis, the first four were independent risk factors for POP. The study also revealed that POP brought about extended duration of postoperative hospitalization.
conclusionThe incidence of POP following PFM microsurgery was significantly high (13.7%). Apart from tumor size (≥3cm) and procedure duration (≥3 h), GCS score (<13) and tumor located in anterior or lateral of brainstem were independent risk factors for POP. Efforts to reduce the duration of surgery, especially among the large tumors located in anterior or lateral of brainstem, may reduce POP rate and hospitalization stay.
