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
background and purposeThis study aimed to evaluate the predictive value of serum substance P (SP) levels at hospital admission for the development of pulmonary infection during hospitalization in patients with acute cerebral infarction. Additionally, the study explored the association between SP levels and the severity of inflammation following pulmonary infection.
methodsA total of 340 patients with acute cerebral infarction were retrospectively analyzed. Serum SP concentrations were measured upon hospital admission. During hospitalization, 96 patients developed pulmonary infections of varying severity, while 244 patients remained free of pulmonary infection. In patients who developed infection, serum levels of high-sensitivity C-reactive protein, procalcitonin, and interleukin-6 were also measured.
resultsInvasive procedures, dysphagia, admission National Institutes of Health Stroke Scale (NIHSS) score, age, and serum SP concentration at admission were identified as significant risk factors for pulmonary infection in patients with acute cerebral infarction. Receiver operating characteristic curve analysis showed that serum SP concentration at admission had a sensitivity of 65.63% and specificity of 85.66% for predicting pulmonary infection (area under the curve=0.81,
conclusionsSerum SP concentration at the time of admission has predictive value for the development of pulmonary infection during hospitalization in patients with acute cerebral infarction and may serve as an early indicator of infection risk.
