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

Research on electron transporting layers (ETLs) for organic solar cells (OSCs) has advanced rapidly in recent years; however, most studies have focused primarily on improving device efficiency rather than stability. Here, we report new ETL polymers, PPV and PPA, incorporating PDINN moieties through vinyl and ethynyl linkers, respectively. Among these materials, PPV-M delivers the best photovoltaic performance, achieving power conversion efficiencies of 18.45% and 16.97% in D18:Y6-BO- and PM6:BTP-eC9-based devices, respectively, surpassing those of PDINN-based counterparts (17.79% and 16.85%). Under thermal aging at 65°C, PPV-M-based devices exhibited improved operational retention compared with PDINN-based devices, with T
