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
backgroundCisplatin is a potent antitumor agent. However, toxicity and primary and secondary resistance are major limitations of cisplatin-based chemotherapy, leading to therapeutic failure. We have previously reported that mono-sulfonamide platinum complexes have good antitumor activity against different tumoral cell lines and with a different and better cytotoxic profile than cisplatin. Besides, N-sulfonamides have been used extensively in medicinal chemistry as bactericides, anticonvulsant, inhibitors of the carbonic anhydrase, inhibitors of histone deacetylases, and inhibitors of microtubule polymerization, among others.
methodsWe aimed to compare the cytotoxic effects of cisplatin and a trans-sulfonamide-platinum-complex (TSPC), in two human melanoma cell lines that differ in their TP53 status: SK-MEL-5, TP53 wild type, and SK-MEL-28, TP53 mutated. We performed cytotoxicity assays with both drugs, alone and in combination, cell cycle analyses, western blotting and immunoprecipitation, and fluorescence immunocytochemistry.
resultsTSPC had similar antiproliferative activity than cisplatin against SK-MEL-5 (3.24 ± 1.08 vs 2.89 ± 1.12 μM) and higher against SK-MEL-28 cells (5.83 ± 1.06 vs 10.17 ± 1.29 μM). Combination of both drugs inhibited proliferation in both cell lines, being especially important in SK-MEL-28, and showing a synergistic effect. In contrast to cisplatin, TSPC caused G1 instead G2/M arrest in both cell lines. Our present findings indicate that the G1 arrest is associated with the induction of CDKN1A and CDKN1B proteins, and that this response is also present in melanoma cells containing TP53 mutated. Also, strong accumulation of CDKN1A and CDKN1B in cells nuclei was seen upon TSPC treatment in both cell lines.
conclusionsOverall, these findings provide a new promising TSPC compound with in vitro antitumor activity against melanoma cell lines, and with a different mechanism of action from that of cisplatin. Besides, TSPC synergism with cisplatin facilitates its potential use for co-treatment to reduce toxicity and resistance against cisplatin. TSPC remains a promising lead compound for the generation of novel antineoplastic agent and to explore its synergism with other DNA damaging agents.
