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

Photomultiplication-type organic photodetectors (PM OPDs), which rely on signal amplification via electron trapping, suffer from a fundamental trade-off: high gain is typically accompanied by a steep increase in dark current under high reverse bias. Here, we overcome this challenge by employing ionic conjugated polyelectrolyte (CPE)-based electron blocking layers (EBLs) with an alternating fluorene-co-triphenylamine backbone. CPE-based EBLs in PM OPDs enable robust dark current stability under reverse bias up to -10 V while maintaining external quantum efficiencies (EQE) exceeding 2000%. Charge-dynamics analysis using Fowler-Nordheim plots reveals that a nanometer-thick CPE layer provides electron-blocking performance comparable to that of a ∼20 nm Al
