The graph could read no effect estimate from its abstract, so it casts no vote on the map.

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
purposeThe increasing number of women living longer with potential side effects of breast cancer treatment highlights the need of a comprehensive assessment of its burden. Therefore, we aimed to quantify the relation between different breast cancer treatments and sleep quality 1 year after diagnosis.
methodsA cohort of 502 newly diagnosed breast cancer patients was prospectively followed. Sleep quality was evaluated with the Pittsburgh Sleep Quality Index (PSQI), at baseline and at the 1-year follow-up. Odds ratios (OR) were computed to quantify the association between patient characteristics and poor sleep quality (PSQI score >5) at baseline, and relative risks (RR) were computed for the association between treatments and the occurrence of poor sleep quality at 1 year.
resultsA total of 60.2% of the patients had poor sleep quality before breast cancer treatments, especially those with anxiety [OR = 2.86, 95% confidence interval (95%CI) 1.92 to 4.27] or depression (OR = 5.25, 95%CI 2.01 to 13.67). Radiotherapy increased the risk of poor sleep quality at 1 year (RR = 3.71, 95%CI 1.15 to 11.96, for a cumulative dose >50 Gy) and there was a tendency for a higher risk in those submitted to chemotherapy, although not statistically significant.
conclusionsOur study shows that sleep disturbances are frequent before cancer treatment and confirms their co-occurrence with other medical conditions, such as anxiety and depression. Different breast cancer treatments increase the risk of impaired sleep quality, therefore contributing to the global disability associated with cancer treatments.
