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
backgroundFibromyalgia (FM) is a rheumatic disorder characterized by widespread persistent pain, hyperalgesia, and allodynia.
objectivesThe aim of this study was to assess the prevalence of FM among Egyptian patients with systemic lupus erythematosus (SLE) and its effect on their health-related quality of life (HRQoL). MATERIALS AND
methodsThis cross-sectional analytical multicenter study was conducted on 550 Egyptian SLE patients. The patients' sociodemographic characteristics, clinical and therapeutic data, and sleeping patterns were collected. SLE disease activity index (SLEDAI) was assessed. We employed the 2016 revisions to the 2010/2011 FM diagnostic criteria to determine the presence of FM and the patients administered the Short-Form Health Survey-36 (SF-36).
resultsThe mean (SD) age was 32.72 (9.90) years, and 91.3% were female. Of 550 Egyptian SLE patients, 119 (21.6%) fulfilled the diagnostic criteria of FM. The FM group was statistically significantly associated with higher age (P = 0.001), body mass index (BMI) (P = 0.008), longer SLE duration (p < 0.001), and higher scores of SLEDAI (p < 0.001). Also, living alone (p < 0.001), chronic psychiatric disease (p = 0.008), chronic kidney disease (p = 0.025), and chronic hemodialysis (p = 0.042) were significantly higher among the FM group. Sleep disorders, such as snoring and sleep apnea, were more prevalent among FM patients. The average sleep hours were significantly lower among the FM group (p < 0.001). FM patients had statistically significantly lower scores across all domains of SF36.
conclusionFM is prevalent among Egyptian SLE patients, and shows significant associations withage, BMI, SLE duration and activity, and disturbed sleep pattern and has a negative impact on their HRQoL. Therefore, early detection and treatment are recommended.
