Imaging-based evaluation of cervical muscle mass and 6-month survival in males with hypopharyngeal carcinoma.
Article in Acta oncologica (Stockholm, Sweden), 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundA significant proportion of newly diagnosed patients with hypopharyngeal carcinoma (HC) are at risk of early death and may not benefit from cancer treatments. Our objective was to assess whether an image-based evaluation of muscle mass could identify patients at risk of impaired survival. MATERIALS AND
methodsThis retrospective study consisted of male patients diagnosed with HC treated at Helsinki University Hospital between 2005 and 2014 (N = 66). Cross-sectional areas of skeletal muscles at the level of the third cervical vertebra (C3) and at the level of the thoracic aortic apex were analyzed using magnetic resonance images and/or computed tomography images. Survival-based cutoff values for low muscle index values were determined using the receiver operating characteristics curves. Kaplan-Meier analyses and Cox proportional hazard models were used to evaluate the associations between the muscle indexes and survival rates.
resultsSeveral muscle indexes were associated with 6-month and 5-year survival. The 6-month survival rate of males with a low sternocleidomastoid muscle index (cutoff 1.73 cm2/m2) was 66%, as opposed to the 97% survival rate for those with an above-the-cutoff muscle index (hazard ratio 13.0 [95% CI 1.5, 116.6]). In a multivariate Cox model adjusted for age, sex, tumor stage, and grade, lower sternocleidomastoid muscle index was significantly associated with decreased 6-month survival.
interpretationC3-level muscle indexes, particularly the sternocleidomastoid muscle index, are a promising marker in the identification of patients at risk of early mortality and could add confidence in decision-making when choosing between active and palliative care.
