Article in Journal of family medicine and primary care. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT04172350 (Developing and Examining Preliminary Effects of An Innovative Care-improvement Smartphone-based Perioperative Solution for Women Undergoing Breast Cancer Surgery), which is not on this 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

Abstract
introductionBreast cancer has been the most common cancer type that affects women worldwide and subsequent treatment is often associated with considerable psychological and quality of life (QoL).
aimThis study aimed to assess psychometric properties of the Arabic version of the European Organization for Research and Treatment of Cancer (EORTC) general QoL questionnaire (QLQ-C30) for breast cancer patients in Qatar. MATERIALS AND
methodsThis is a cross-sectional hospital-based study conducted on 678 breast cancer patients using Arabic version of the EORTC QLQ-C30 tool.
resultsThe mean age of women was 47.7 ± 10.2 years and 33.4% of women had consanguineous parents. Six subscales out of the nine met the standards of reliability with coefficients ranging from 0.55 to 0.89. The mean score of all functioning scales was high >55. Advanced breast cancer stages of III-IV had higher symptomatic scores significantly than those in early stages for the physical function, cognitive, fatigue, insomnia, appetite loss, constipation, and financial difficulties. Correlation coefficients between each item ranged from -0.113 to 0.960, and item 21 (tense) and item 23 (irritable) had strongest negative correlations with their corresponding emotional functioning subscale, whereas items 29 (physical condition) and 30 (overall QoL) had the strongest positive correlation with Global Health/QoL subscale. Item 6 (limited work) showed a higher correlation with fatigue (
conclusionQatari Arabic version of the EORTC QLQ-C30 showed acceptable psychometric properties, which is a reliable and valid instrument, that can be used by oncologists.
