1 · What the graph read from it

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.

2 · The registry

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

backgroundLittle is known about factors affecting adherence to highly-structured and supervised exercise programs in older people.

methodsHealthy, inactive older (≥65 y) women (N = 30) were randomized into a 1) higher- (ATH-80% VO₂peak); 2) moderate- (ATM-65% VO₂peak) intensity aerobic; or 3) lower-intensity resistance (RTL; 50% VO₂peak) group. All 3 groups exercised 4 days·week⁻¹ for an average of 45 to 70 min·session⁻¹ over 9 months. Adherence (%) was defined as the proportion of prescribed sessions (N = 144) in which subjects achieved their 1) prescribed heart rate (intensity adherence) and 2) their prescribed duration (duration adherence). Primary determinants of adherence included prescribed intensity (METs) and prescribed duration (min), as well as age, body composition, VO₂peak, and exercise self-efficacy score.

resultsIntensity adherence was nearly 100% for all 3 groups, while duration adherence was 95%, 91%, and 85% in the RTL, ATH, and ATM groups, respectively. Prescribed exercise duration was the strongest determinant of duration adherence (r = -0.72; P < .0001), independent of prescribed METs, age, VO₂peak, and body composition.

conclusionsDue to competing lifestyle demands, exercise intensity may be less of a factor in adherence among older women than is exercise duration.
