Survival of Patients with First and Metachronous Second Primary Breast Cancer or Lung Cancer Malignancy: Comparisons Using the SEER Database.
Article in Advances in therapy, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
introductionBreast cancer (BC) and lung cancer (LuC) are common malignancies. The survival of patients with metachronous second primary malignancy (MSPM) of BC and LuC after a first primary of BC and LuC remains unclear.
methodsData of patients with BC and LuC, with or without MSPM of BC and LuC, who were diagnosed from 2000 to 2014, were extracted from the Surveillance, Epidemiology, and End Results (SEER) database. The baseline characteristics of the different groups were compared using chi-square tests. The survival curves were compared using the log-rank test. Survival analysis was also performed in other malignancies with data extracted from the SEER database using the same method.
resultsSignificant differences in most of the demographics and clinicopathological factors were found between the groups. Patients with LuC with an MSPM of BC (LuC2BC) exhibited better survival than those with LuC (P < 0.001), while patients with BC with an MSPM of LuC (BC2LuC) exhibited worse survival than those with BC (P < 0.001). A similar trend was found in other malignancies. Prostate cancer (PC) followed by thyroid cancer (TC) (PC2TC) and TC followed by PC (TC2PC) did not show an obvious survival trend against their index malignancy (IM).
conclusionsMSPM benefits the IM prognosis if the survival rate of MSPM is better than that of the IM and vice versa. However, the situation is somewhat confusing when the survival differences between MSPM and IM are minimal.
