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
introductionThis study explored the impact of a caregiver educational intervention on improving the quality of life (QoL) of caregivers of community-dwelling activity-limited older adults.
methodsThis non-randomized, controlled quasi-experimental study with geographically defined groups was conducted in two selected secretariat divisions of the Colombo District in the Western Province of Sri Lanka. The sample of caregivers (N = 72) for the intervention (n = 36) and control (n = 36) groups was selected depending on the highest degree of activity limitations in older adults. The need-based educational intervention delivered to the intervention group consisted of 2-4 sessions (two weeks apart) with live demonstrations. The QoL of both groups was assessed with the Sinhala-validated WHOQOL-BREF questionnaire before and 6 months after the intervention. Data were analyzed by SPSS 20 using Mann-Whitney U and Wilcoxon signed-rank tests to compare mean scores.
resultsThe mean±SD age of the caregivers was 55.75±12.9 years; the majority were female (80.6%, n = 58), 44.4% (n = 32) were unknown to have a chronic disease, while 26.4% (n = 32) and 27.8% (n = 19) reported having 2 and 3 chronic diseases, respectively. Many caregivers (77.8%, n = 56) perceived their health as satisfactory. Six months after the educational intervention, scores had significantly higher ratings in the overall QoL (61.97±10.33 vs. 51.61±10.99), physical health (68.55±12.39 vs. 54.76±11.32), psychological (69.21±12.04 vs. 54.86±11.89) and social relationships domains (46.06 ±16.72 vs. 34.49 ±17.94) in the intervention group compared to controls (p < 0.01). No significant change was observed in the environmental domain (64.06±12.21 vs. 62.33±11.45; p > 0.05) between the two groups. Pre- vs. post-intervention scores of the overall and the four domains of QoL showed a significant increase in the intervention group (p < 0.001), whereas scores of overall QoL and all three domains except the environmental domain showed a significant decline (P < 0.001) after 6 months when compared to pre-6 months values in the control group.
conclusionsThe caregiver educational intervention positively changes the QoL of caregivers of activity-limited older adults. The involvement of healthcare professionals in caregiver education will improve the QoL of caregivers through knowledge enhancement.
