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
Pediatric inflammatory multisystem syndrome temporally associated with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2; PIMS-TS) is a novel condition with persistent fever, inflammation, and single or multiorgan dysfunction. We aimed to describe the characteristics of children more severely affected and our clinical approach. We retrospectively collected clinical, treatment, and early outcomes data during a 3-month period in a pediatric intensive care unit (PICU) of a tertiary university hospital in Portugal. Twelve children who fulfilled the Royal College of Pediatrics and Child Health case definition were hospitalized, seven needed PICU admission. Median age was 13 years and three were overweight, with no other comorbidity. All had positive immunoglobulin G antibodies for SARS-CoV-2. All presented with prolonged fever, asthenia, hypotension, and shock. Other prominent symptoms were abdominal complaints and rash. All patients had leukocytosis, neutrophilia, and marked elevation of inflammatory markers. Cardiac involvement was observed in all patients with elevated levels of troponin and B-type natriuretic peptide along with left ventricular hypokinesis. Depressed left ventricular function was observed in four patients. All patients received broad-spectrum antibiotics, intravenous immunoglobulin, methylprednisolone, low-dose aspirin, and vasoactive medications. Four patients received prophylactic enoxaparin. All patients needed supplementary oxygen; however, high-flow oxygen therapy and noninvasive ventilatory support with positive end-expiratory pressure were required in three and two patients, respectively. Five patients required invasive mechanical ventilation. The mean duration of PICU stay was 7.1 days. The median Pediatric Risk of Mortality-III score was 9 and no mortality was observed. PIMS-TS demands a prompt and multidisciplinary approach. Risk factors, best clinical pathway, and long-term complications are still unknown.
