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
purposeTo investigate the fatigue trajectory types and various influencing factors during intensity-modulated radiotherapy (IMRT) in patients with nasopharyngeal carcinoma (NPC).
methodsLongitudinal data of cancer-related fatigue from 182 participants with NPC were assessed at baseline (T0) and weekly (T1-T7) during radiotherapy via the revised Piper Fatigue Scale. Patient-generated data from the Subjective Global Assessment (PG-SGA) and the Hospital Anxiety and Depression Scale were collected at baseline. Latent growth curve models (LGCM) and latent class growth models (LCGM) were used to explore fatigue trajectories and heterogeneity among fatigue trajectories, respectively. The influencing factors of different trajectories were assessed via multivariate logistic regression analysis.
resultsThe overall fatigue level during IMRT tended to increase but then decreased, as indicated by the LGCM results (S = 0.985, P < 0.001), and peaked in the fifth week. The LCGM results fit the following three fatigue trajectories: "mild fatigue persistence" (n = 54, 29.7%), "mild fatigue growth" (n = 95, 52.2%), and "moderate fatigue persistence" (n = 33, 18.1%). PG-SGA score and being married were risk factors for the "mild fatigue growth" group. The risk factors for the "moderate fatigue persistence" group were PG-SGA, anxiety, and being married, whereas a family income < 3000 Y/month was a protective factor.
conclusionsThree types of fatigue trajectories are observed during IMRT in patients with NPC. PG-SGA score, marital status, anxiety, and family income may influence the type of fatigue trajectory in patients, so preventive measures should be taken on the basis of specific circumstances.
