The association of zero walking cadence minutes with sleep quality in adults 18-65.
Article in Sleep & breathing = Schlaf & Atmung, 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
purposePhysical activity (PA) guidelines suggest a link between PA, sedentary time, and sleep quality (SQ). Step cadence is an emerging proxy for PA intensity, with zero cadence (ZC) indicating sedentary time. No research has explored the relationship between ZC and SQ. This study examines the relationship between ZC and SC, compared to traditional PA and sedentary metrics, all measured via accelerometry.
methodsSleep and PA was assessed in 138 adults (53 male, 85 female, age = 23.5 ± 8.0 year.) via accelerometry. Sedentary, light, moderate, vigorous intensity PA, and ZC minutes per day were measured. SQ variables included sleep efficiency (SE), total sleep time (TST), and minutes of awake time after sleep onset (WASO). Correlation analysis and analysis of covariance was used to assess relationships between study variables and to assess differences in PA and sedentary behavior between normal and poor sleepers.
resultsSedentary time was negatively associated with SE (r = -0.24, P < 0.05) and TST (r = -0.51, P < 0.001). ZC was negatively associated with SE (r = -0.25, P < 0.05), TST (r = -0.39, P < 0.001) and positively associated with WASO (r = 0.17, P < 0.001). Poor sleepers accumulated greater ZC minutes than normal sleepers when categorized by SE (555.9 ± 69.1 vs. 521.6 ± 83.7, P = 0.02)) or TST (570.4 ± 77.7 vs. 524.5 ± 76.7, P < 0.01).
conclusionResults suggest that zero cadence minutes is a viable metric for assessing sedentary time and may be of greater utility to more traditional measure of sedentary time.
