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

Inorganic perovskites are known for their excellent photothermal stability; however, the photothermal stability of all-inorganic n-i-p perovskite solar cells (PSCs) is compromised due to ion diffusion and free radical-induced degradation caused by the use of doped spiro-OMeTAD hole transport materials (HTMs). In this study, two isomeric donor-acceptor-donor (D-A-D) type small molecules, namely HBT and HiBT, were developed and used as dopant-free HTMs, using 2,1,3-benzothiadiazole or benzo[d][1,2,3]thiadiazole as acceptor moieties. The HiBT molecule, with its symmetry-breaking features, exhibits a large dipole moment, enhanced coordination-active sites, and a well-aligned energy level structure, all of which contribute to passivating perovskite surface defects and improving free charge separation. As a result, inorganic CsPbI
