1 · What the graph read from it

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.

2 · The registry

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

backgroundAlthough the platinum regimen is adopted widely nowadays in spite of the excessive side effects, there is still no international standard for palliative chemotherapy of advanced gastric cancer. This meta-analysis assessed the efficacy and tolerability of platinum versus non-platinum chemotherapy as first-line palliative treatment in patients with inoperable, advanced gastric cancer.

methodsRandomized phase II and III clinical trials on first-line palliative chemotherapy in inoperable, advanced gastric cancer were identified by electronic searches of PubMed, Embase, and the Cochrane Controlled Trial Register, and hand searches of relevant abstract books and reference lists. Response rates, overall survival, and toxicity were analyzed. Depending on whether new-generation agents (S-1, taxanes and irinotecan) were utilized, the non-platinum regimens were divided into two subgroup.

resultsCompared to non-platinum regimens containing new-generation agents, the use of platinum-based regimens was associated with better response (risk ratio (RR) = 1.94, 95%CI[1.48, 2.55], p<0.001), an increase of overall survival (hazard ratio (HR) = 0.85, 95%CI[0.78, 0.92], p<0.001), a higher risk of hematological and non-hematological toxicity. No statistically significant increase in response (RR = 1.03, 95%CI [0.85, 1.24], p = 0.76) or overall survival (HR = 1.07, 95%CI [0.88, 1.30], p = 0.49) was found when platinum therapies were compared to new-generation agent based combination regimens. The toxicity of platinum-based regimens was significantly higher for hematologic toxicity, nausea and vomiting, and neurotoxicity, but not for diarrhea and toxic death rate.

conclusionNew-generation agent based combination regimens achieved similar response rate and overall survival as platinum-based therapy that had generally higher side effects. S-1, taxanes and irinotecan seemed to be valid options for patients with inoperable, advanced gastric cancer as first-line chemotherapy.
