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
introductionCancer-related fatigue (CRF) is a frequent, subjective, and difficult-to-manage symptom, for which few interventions have proven effective. Recent evidence suggests that electroacupuncture (EA) can reduce fatigue, although specific studies on this technique remain scarce.
objectiveTo evaluate the efficacy of EA in treating CRF in cancer patients.
methodsA systematic review registered in PROSPERO was conducted, including clinical trials assessing the effects of EA in patients with CRF. Searches were performed in the PubMed, Embase, Virtual Health Library, Scopus, and CAPES databases, with no restrictions on date, language, sex, ethnicity, or type of cancer. We assessed the methodological quality using the PEDro scale and evaluated the risk of bias using the RoB-2 tool.
resultsA total of 2,110 studies were identified. After applying inclusion criteria, five trials were included: three randomized, one non-randomized, and one single-arm clinical trial. In total, 251 patients were analyzed, 132 of whom received EA treatment. Interventions varied from two to three weekly sessions, each lasting 20 to 30 minutes, over a period of four to eight weeks. Acupuncture points and electrical frequencies (0.2-25 Hz) differed between studies. Outcomes were measured by the Brief Fatigue Inventory, Functional Assessment of Cancer Therapy - Fatigue, and European Organization for Research and Treatment of Cancer Quality of Life Questionnaire. Despite the potential benefits observed in EA-treated groups, the findings remain inconsistent.
conclusionEA shows promising therapeutic potential for managing CRF. However, the small number of studies, methodological heterogeneity, and small sample sizes limit generalizability. Multicenter clinical trials with larger samples and standardized protocols are needed to confirm efficacy.
