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

Organic semiconductors are widely regarded as a key material platform for next generation flexible and wearable electronics. Realizing high-resolution, well-defined patterns is essential to scale organic field effect transistors for higher device density and greater electrical performance. Conventional photolithographic patterning technologies typically face the challenges of chemical contamination induced by photoresist, developers and chemical etchant. Here, we report a resist-free, maskless patterning approach for pentacene based on thermal scanning probe lithography (t-SPL), exploiting the localized thermochemical conversion of the soluble precursor 13,6-N-sulfinylacetamidopentacene into pentacene. By tuning key t-SPL parameters, including probe loading conditions and scanning velocity, well-defined pentacene nanostructures with a minimum full width at half maximum of 200 nm were achieved. Directly patterned pentacene channels were further integrated into field-effect transistors, demonstrating electrical functionality. This work establishes t-SPL as a viable route for direct, high-resolution patterning of organic semiconductors and provides a promising pathway toward further miniaturization and integration of organic electronic devices.
