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
introductionCutaneous lupus erythematosus (CLE) is a chronic inflammatory autoimmune disease with not fully understood pathogenic mechanisms. The lesions in CLE are mainly located on the facial skin, that is why searching for noninvasive methods to facilitate differential diagnosis is justified. High-frequency ultrasonography (HFUS) is a noninvasive diagnostic tool, enabling the assessment of all skin layers without leaving a scar, in contrast to skin biopsy, which is the gold diagnostic standard in this disease. The aim of this study was to assess the usefulness of HFUS in the diagnostic process of patients with CLE, taking into account individual types of the disease, its severity and activity. MATERIALS AND
methodsFor the purpose of analyzing the HFUS results, the studied lupus erythematosus (LE) group was divided into three subgroups: acute cutaneous lupus erythematosus (ACLE), subcutaneous lupus erythematosus (SCLE), and chronic cutaneous lupus erythematosus (CCLE). Fifty-seven active lesions and nine inactive lesions were examined. The analysis was performed using a 20 MHz Dermascan C linear head (version 3) (Cortex Technology; Hadsund, Denmark). In the analysis of the HFUS image, skin thickness, echogenicity of the skin, and the presence and thickness of subepidermal low echogenic band (SLEB) were taken into consideration. The image was compared with the healthy skin of the contralateral area and, if this was not possible, with the skin in the area of the lesion.
resultsHFUS images of 17 patients with active CLE (29.8%) showed the presence of SLEB and a statistically significant relationship between SLEB thickness and disease activity expressed by Cutaneous Lupus Erythematosus Disease Area and Severity Index (CLASI-A) (p = 0.022). The average skin thickness of active foci was significantly greater than the average thickness of healthy skin (p = 0.001). Additionally, in the group of patients with CCLE, 55.6% showed increased skin echogenicity, showing its statistically significant inverse correlation with CLASI-A (p = 0.004).
conclusionsSLEB can be treated as an indicator of the activity of the disease process. HFUS allows the assessment of certain features of healthy and diseased skin without performing a biopsy, but it cannot replace histological examination in the case of CLE diagnosis.
