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 analyze continuous exosomatic electrodermal activity (EDA) without external stimuli (EDAcw) in patients with primary hyperhidrosis before and after sympathectomy.
methodsThis prospective study included 28 participants, categorized into two groups. The first group comprised 18 patients with palmoplantar hyperhidrosis who underwent bilateral thoracic sympathectomy. The second group (control) consisted of 10 patients. Two questionnaires were administered: the Control Group completed them once, whereas the Sympathectomy Group completed them preoperatively, and on the first and thirtieth postoperative days. Sweating was evaluated by measuring EDAcw using an MP36R biosensor. Measurements were obtained from the hands and feet for 5 min without external stimuli in an air-conditioned environment and were performed preoperatively, and on the first and thirtieth postoperative days. Anthropometric, clinical, and surgical data were collected, and no significant sociodemographic differences were observed between the groups.
resultsIn the Sympathectomy Group, quality of life improved, and sweating reduced. During preoperative assessment, EDA was higher in the hands and feet of patients with hyperhidrosis than in the Control Group. Postoperatively, EDA in the hands decreased, with 100% of the patients showing a decrease in sweating. For the feet, 67% of the patients reported reduced sweating, and 44% showed a statistically significant decline in EDA.
conclusionContinuous exosomatic EDA measurement without external stimuli is a suitable method for assessing patients with palmoplantar hyperhidrosis and shows appropriate clinical correlation.
