Determination of Tumor Dose Response Thresholds in Patients with Chemorefractory Intrahepatic Cholangiocarcinoma Treated with Resin and Glass-based Y90 Radioembolization.
Article in Cardiovascular and interventional radiology, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT05422690 (A Phase II Single-center, Open-label, Single Arm Study of Induction Gemcitabine, Cisplatin and Durvalumab Followed by Gemcitabine, Cisplatin and Yttrium-90), which is not on this map.

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
purposeTo compare the efficacies of glass and resin-based Yttrium-90 microspheres by comparing absorbed tumor dose (TD) with both tumor response (TR) and overall survival (OS) in patients with chemorefractory intrahepatic cholangiocarcinoma (ICC).
methodsPost-Y90 treatment bremsstrahlung SPECT/CT of 38 consecutive patients receiving 45 treatments (21 resin microspheres, 24 glass microspheres) were analyzed retrospectively. MIM software v6.9.4 (MIM Software Inc, Cleveland, OH) was used to calculate targeted tumors' dose volume histogram. Modified Response Evaluation Criteria in Solid Tumors was used to evaluate tumor response 3 months post-treatment. Kaplan Meier estimation was used for survival analysis. T-test was used to compare the devices on various dosimetric parameters.
resultsThresholds for TD to predict TR with ≥ 80% specificity were as follows: mean TD (Resin: 78.9 Gy; Glass: 254.7 Gy), maximum TD (Resin: 162.9 Gy; Glass: 591 Gy), minimum TD (Resin: 53.7 Gy; Glass: 149.1 Gy). Microsphere type had no effect on survival from first Y90 (Resin: 11.2 mo; Glass 10.9 mo [p = 0.548]). In patients receiving resin microspheres, mean TD ≥ 75 Gy or maximum TD ≥ 150 Gy was associated with median OS of 20.2 mo compared to 6.5 mo for those receiving less (p = 0.001, 0.002, respectively). For patients treated with glass microspheres, those receiving a mean TD ≥ 150 Gy had a median OS of 14.6 mo vs. 2.6 mo for those receiving less (p = 0.031).
conclusionTD thresholds predictive of TR and OS differ significantly between glass and resin microspheres. However, microsphere type has no impact on survival in patients with chemorefractory ICC. LEVEL OF EVIDENCE: Level 3, Retrospective Study.
