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

Preclinical models play a critical role in the development of PSMA-targeted radiopharmaceuticals for prostate cancer. However, many existing models have practical limitations, including slow tumor growth, low engraftment rates, and restricted availability, and all human PSMA-positive lines are confined to immunodeficient hosts. We developed and characterized a novel PSMA-expressing transgenic cell line, CT26-PSMA, as a practical tool for preclinical screening of PSMA-targeting agents. The CT26-PSMA cell line was established by stable transfection of the murine colon carcinoma CT26 cell line with human PSMA using the Sleeping Beauty transposon system. PSMA expression was confirmed by RT-qPCR (reverse transcription quantitative polymerase chain reaction), flow cytometry, and radioligand saturation binding on intact cells. Two [
