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

contextSound levels in fitness classes often exceed safe levels despite studies that show many participants find high sound levels stressful.

aimsThe objective is to determine if lower sound levels in spinning classes significantly impact exercise intensity and to determine if class participants prefer the music played at lower levels. SETTINGS AND

designObservational study of 1-hour group spin classes. METHODS AND MATERIALS: Sound levels were measured in 18 spin classes over two weeks. No adjustments were made in week-1 and sound levels were decreased by 3 dB in week-2. Participant preferences and data on post-class hearing changes were collected via post-class questionnaires (n = 213) and divided into three terciles based on the total sound exposure of corresponding classes. STATISTICAL ANALYSIS USED: Unweighted survey generalized linear models are used to sort the causal relationships between different variables simultaneously and participant responses. The Chi-square test is used to reveal statistically significant relationships between two or more categorical variables.

resultsWhen mean sound levels exceeded 98.4 dBC, respondents were 23 times more likely to report the music as too loud than too quiet (P < 0.05), and four times more likely to prefer a decrease, rather than an increase, in sound level (P < 0.05). There was no significant difference in respondents reporting high exercise intensity between the middle (95.7-98.1 dBC) and upper (98.4-101.0 dBC) terciles, 67.1% and 71.8%, respectively (P = 0.53). Overall, 25.9% of respondents reported auditory symptoms following classes. Analysis in the context of dBA and dBC produced congruent conclusions and interpretations.

conclusionsSound levels in many fitness classes remain dangerously high. However, music level can be lowered without a significant impact on perceived exercise intensity and many participants prefer lower sound levels than current levels.
