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.
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
Carbonic anhydrase IX (CAIX) is an interesting therapeutic target in clear cell renal cell carcinoma (ccRCC), but gastrointestinal uptake impedes the clinical translation of CAIX-targeted radioligand. In this study, structure-guided optimization of a cyclic peptide scaffold was conducted to decouple tumor targeting from gastrointestinal retention. Methods: Five novel CAIX-targeting ligands were developed at the base of a cyclic peptide and evaluated in OS-RC-2 cell, small animal positron emission tomography/computed tomography (PET/CT), biodistribution, and radiotherapy experiments. The lead candidate was tested on 21 patients with cancer in comparison to Results: In preclinical experiments, ⁶⁸Ga/¹⁷⁷Lu-ZH2 exhibited sub-nanomolar CAIX affinity and a favorable pharmacokinetics, with preserved tumor uptake and markedly reduced gastrointestinal retention, compared with benchmark ⁶⁸Ga/¹⁷⁷Lu-DPI-4452. In mice, ¹⁷⁷Lu-ZH2 inhibited tumor growth and prolonged survival without evident toxicity. In a first-in-human study of 21 patients with renal masses, ⁶⁸Ga-ZH2 PET/CT was deemed safe and demonstrated a superior diagnostic performance to ¹⁸F-FDG, detecting additional primary tumors and metastases with higher contrast. Conclusions: These results establish
