The effect of progressive resistance training on lean soft tissue mass in head and neck cancer patients during concomitant chemoradiotherapy: the DAHANCA 31 randomized controlled trial.
Trial report in Acta oncologica (Stockholm, Sweden), 2026. 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
background and purposeHead and neck cancer patients undergoing concurrent chemoradiation treatment (CCRT) lose a significant amount of lean soft tissue mass (LSTM) reducing muscle strength and performance. Progressive resistance training (PRT) may mitigate this loss and improve muscle strength and performance. The purpose was to investigate the effects of PRT initiated at CCRT onset on LSTM, muscle strength, and functional performance compared with usual care. PATIENTS/MATERIAL AND
methodsPatients were randomized to 12 weeks of PRT (36 sessions) or usual care with no exercise (control group [CON]). At baseline, after 6 and 12 weeks, 6 and 12 months, Dual-Energy Absorptiometry evaluated total body mass (BM), LSTM, and fat mass (FM); 1 repetition maximum (1RM) chest press and leg press test assessed maximal muscle strength and functional performance (30 seconds chair-rise; 30 seconds arm curls; stair climb) was evaluated. Dietary intake was registered as were Quality of Life questionnaires European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (QLQ) C30 and QLQ H&N-35. A sample size of 72 patients (36 per group) was determined a priori with LSTM as the primary endpoint.
resultsFifty patients were included (required sample size was not met), 25 in each group. From baseline to 12 weeks, patients in the PRT group lost 8.6 ± 1.0 kg BM (10%), 3.4 ± 0.6 kg LSTM (6%), and 5.2 ± 0.8 kg FM (21%). This was not significantly different from the CON group losing 7.4 ± 1.0 kg BM (9%), 3.4 ± 0.6 kg LSTM (6%), and 4.0 ± 0.8 FM (17%). Likewise, 1RM decreased equally in both groups. Chair rise and arm curl performance improved significantly more in PRT compared with in CON (p < 0.05).
interpretationIn this study PRT initiated at CCRT onset did not attenuate loss of LSTM or muscle strength. However, PRT did result in significantly increased functional performance.
