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
purposeDMS612 is a dimethane sulfonate analog with bifunctional alkylating activity and preferential cytotoxicity to human renal cell carcinoma (RCC) in the NCI-60 cell panel. This first-in-human phase I study aimed to determine dose-limiting toxicity (DLT), maximum tolerated dose (MTD), pharmacokinetics (PK), and pharmacodynamics (PD) of DMS612 administered by 10-minute intravenous infusion on days 1, 8, and 15 of an every-28-day schedule. EXPERIMENTAL
designPatients with advanced solid malignancies were eligible. Enrollment followed a 3+3 design. PKs of DMS612 and metabolites were assessed by mass spectroscopy and PD by γ-H2AX immunofluorescence.
resultsA total of 31 patients, including those with colorectal (11), RCC (4), cervical (2), and urothelial (1) cancers, were enrolled. Six dose levels were studied, from 1.5 mg/m(2) to 12 mg/m(2). DLTs of grade 4 neutropenia and prolonged grade 3 thrombocytopenia were observed at 12 mg/m(2). The MTD was determined to be 9 mg/m(2) with a single DLT of grade 4 thrombocytopenia in 1 of 12 patients. Two patients had a confirmed partial response at the 9 mg/m(2) dose level, in renal (1) and cervical (1) cancer. DMS612 was rapidly converted into active metabolites. γ-H2AX immunofluorescence revealed dose-dependent DNA damage in both peripheral blood lymphocytes and scalp hairs.
conclusionsThe MTD of DMS12 on days 1, 8, and 15 every 28 days was 9 mg/m(2). DMS612 appears to be an alkylating agent with unique tissue specificities. Dose-dependent PD signals and two partial responses at the MTD support further evaluation of DMS612 in phase II trials.
