Effect of strength-based physical exercise on telomere length as a marker of premature ageing in patients with schizophrenia: study protocol for a pilot randomised controlled trial.
Article in BJPsych open, 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
backgroundPatients with schizophrenia die decades earlier than the general population. Among the factors involved in this mortality gap, evidence suggests a telomere length shortening in this clinical population, which is associated with premature ageing. Recent studies support the use of strength-based training exercise programmes to maintain, or even elongate, telomere length in healthy elderly populations. However, studies aiming at modifying telomere length in severe mental illnesses, such as schizophrenia, are still very scarce.
aimsTo investigate the effect of a strength-based physical exercise programme on the telomere length of individuals with schizophrenia.
methodWe propose a pragmatic, randomised controlled trial including 40 patients aged ≥18 years, with a stable diagnosis of schizophrenia, attending the Complejo de Rehabilitación Psicosocial (CRPS, Psychosocial Rehabilitation Centre) in Salamanca, Spain. These patients will be randomly assigned (1:1) to either receive the usual treatment and rehabilitation programmes offered by CRPS (treatment-as-usual group) or these plus twice weekly sessions of an evidence-based, strength-based training exercise programme for 12 weeks (intervention group). The primary outcome will be effect on telomere length. Secondary outcomes will include impact on cognitive function, frailty and quality of life.
resultsWe expect to show the importance of implementing strength-based physical exercise programmes for patients with schizophrenia. We could find that such programmes induce biological and genetic changes that may lengthen life expectancy and decrease physical fragility.
conclusionsWe anticipate that our trial findings could contribute to parity of esteem for mental health, reducing premature ageing in patients with severe mental illnesses, such as schizophrenia.
