Association of dysautonomia and different risk factors in patients with Guillain-Barré syndrome in a tertiary hospital in the Philippines.
Article in BMC neurology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
backgroundGuillain-Barré syndrome (GBS) presents with progressive ascending weakness, but it can also present with dysautonomia such as tachycardia, blood pressure fluctuations, diaphoresis, ileus, and urinary retention. GBS patients with dysautonomia was observed to have longer hospital stays and higher mortality rates than those without dysautonomia. We aimed to determine the risk factors for dysautonomia and its manifestations among patients with GBS and compared their features to those without dysautonomia.
methodsWe conducted a 10 year-retrospective review of GBS patients admitted at the Philippine General Hospital. The patient demographics, comorbidities, GBS disability status scale (GBS-DS), GBS variants, parameters of dysautonomia, treatment, and outcome were recorded and analyzed. Simple and multiple logistic regression analysis were conducted to determine the factors associated with dysautonomia and the relationships were expressed using odds ratio.
results71 patients were included, and 49% developed dysautonomia. Hypertension and tachycardia were the most prominent manifestations. There was an increase in the odds of developing dysautonomia in a one-year increase in age (OR: 1.11, p = 0.001) and a point increase in GBS-DS (OR:1.65, p = 0.037) during admission. Pre-morbid hypertension (OR:0.13, p = 0.028) and alcoholism (OR: 0.17, p = 0.037) are shown to decrease the odds of developing dysautonomia. Although GBS patients with dysautonomia had longer hospital stay (12.33 days), it only predicts 5.5% of the variability. DISCUSSIONS: The prevalence of cardiovascular manifestations was postulated from cardiosympathetic hyperactivity between arterial baroreceptors, cardiac parasympathetic fibers, and preganglionic sympathetic vasomotor fibers. The protective mechanism of premorbid hypertension could be attributed to the prior intake of antihypertensive medications, which mitigate cardiosympathetic fluctuations, while the protective effect of alcoholism needs to be further studied.
conclusionPatients who are older and with a high GBS-DS on admission, prompt close monitoring for the development of dysautonomia. The protective effects of premorbid hypertension and alcoholism needs further evaluation. The odds of developing pneumonia and being on a mechanical ventilator, while not statistically significant, could contribute to longer hospital stay of patients with dysautonomia. A larger prospective study is warranted to confirm these results.
