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.

2 · The registry

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

This research provides a techno-economic and environmental evaluation of a large-scale hybrid renewable energy system (HRES) to support sustainable coastal development in Egypt, considering Ras El-Hekma as a representative case study. Six hybrid system configurations, including both grid-connected and off-grid modes, are modeled and evaluated using HOMER Pro. A large-scale load profile is developed with a peak demand of 28.8 MW and an annual electricity consumption of approximately 100.46 GWh over a 20-year project lifetime. The simulation results indicate that the optimal configuration is a 15 MW grid-connected wind energy system, achieving a Cost of Energy (COE) of $0.03409/kWh and a Net Present Cost (NPC) of $37.46 million with an initial investment cost of $24.8 million. The proposed system also achieves a renewable energy fraction of 68.6% and reduces CO₂ emissions by 60.45% compared with the base case grid-only scenario. Sensitivity analysis reveals that wind speed, project lifetime, inflation rate, and discount rate are the most influential factors affecting system feasibility and economic viability. The results demonstrate the strong potential of large-scale HRESs for sustainable energy development across Egypt's coastal megaprojects.
