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.

Abstract
HA121-28, a promising multikinase inhibitor, mainly targets rearranged during transfection (RET) fusions and selectively targets vascular endothelial growth factor receptor-2, endothelial growth factor receptor, and fibroblast growth factor receptor 1-3. The safety, pharmacokinetics, and efficacy of HA121-28 were assessed in advanced solid tumors (phase 1, ClinicalTrials.gov NCT03994484) and advanced RET fusion-positive non-small-cell lung cancer (RET-TKI naive NSCLC, phase 2, ClinicalTrials.gov NCT05117658). HA121-28 was administered orally in doses range from 25 to 800 mg under the 21-day on/7-day off scheme for a 28-day cycle in phase 1 trial. The recommended dose identified in phase 1 (450 mg) was administered for patients during phase 2. The primary endpoints were the maximum tolerated dose (MTD) in phase 1 and the objective response rate (ORR) in phase 2. 162 patients were enrolled in phase 1 and 48 in phase 2. A total of 600 mg once daily was set as MTD. Across 100-800 mg, the exposure of HA121-28 increased in a dose-dependent manner. Consistent between both trials, diarrhea, rash, and prolonged QTc interval, were the most reported treatment-emergent adverse events. 40.0% (phase 1) and 62.5% (phase 2) patients experienced grade ≥3 treatment-related adverse events, respectively. The overall ORR was 26.8% and the median progression-free survival (PFS) was 5.5 months among 97 NSCLC patients with advanced RET fusion receiving a dose at ≥450 mg once daily. HA121-28 showed encouraging efficacy in advanced RET fusion NSCLC and its toxicity was tolerable in most patients. Nevertheless, cardiotoxicity is a notable concern that warrants careful attention.
