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.

Abstract

STUDY

objectivesTime-restricted eating (TRE) is a novel dietary intervention targeting weight loss and cardiometabolic risk factors. The impact of TRE on sleep patterns remains under-explored.

methodsThis was a post hoc analysis of a parallel-arm, controlled feeding trial in 41 adults with obesity and prediabetes/diabetes, randomized to TRE (08:00 am-06:00 pm) or usual eating pattern (UEP; 08:00 am-12:00 am) for 12 weeks. We objectively determined sleep-wake patterns from 7-day wrist actigraphy data obtained at baseline and week 12. From this data, we derived total sleep time (TST) and sleep midpoint over a 24-hour period, sleep onset/offset, and sleep continuity measures. We used paired t-tests or Wilcoxon signed rank tests to compare data between baseline and week 12 within intervention arms and Mann-Whitney U tests or Wilcoxon signed rank tests to compare changes between intervention arms.

results38 participants (20 UEP; 18 TRE; 93% of those randomized in the parent trial) with adequate actigraphy data (mean age 59.6 ± 7.3 years, 92% female, 92% Black, mean BMI 36.3 ± 4.7 kg/m2) were analyzed. Compared to UEP, TRE increased TST by 55 minutes (p = .03). TRE shifted sleep midpoint to 44 minutes earlier, from 03:24 am to 02:40 am (p = .01), while UEP maintained the same sleep midpoint at 03:15 am. Sleep onset shifted from a median of 12:22 am to 11:52 pm in TRE (p = .03) while it remained stable in UEP (p = .97). There were no differences in sleep offset and sleep continuity within and between intervention arms.

conclusionsTRE increased sleep time and caused earlier sleep onset compared to UEP, revealing how the timing of eating may affect sleep timing and duration.
