Bright light shows promise in improving sleep, depression, and quality of life in women with breast cancer during chemotherapy: findings of a pilot study.
Trial report in Chronobiology international, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT02658708 (Bright Light on Fatigue in Women Being Treated for Breast Cancer), which is not on this map. Cited by 12 papers, 1 of them a synthesis that pooled 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.
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.

Abstract
Sleep and fatigue-associated symptoms are prominent during chemotherapy. The purpose of this pilot study was to examine bright light effects on sleep disruption, fatigue, daytime sleepiness, depression, and quality of life (QOL) in women with stage I-III breast cancer undergoing chemotherapy. In this 2-group randomized controlled trial (NCT02658708), participants were randomized to receive either blue-green light of 12,000 lux (experimental) or dim red light of 5 lux (control). Light therapy was self-administered using a light visor cap at home. Both groups received 30-minute daily light therapy for 21 consecutive days following the 2
