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

backgroundThis study aimed to compare the survival outcomes between squamous cell carcinoma (SCC) and adenocarcinoma/adenosquamous carcinoma (AC/ASC) of the cervix after radical radiotherapy and chemotherapy.

methodsPropensity score matching (1:4) was used to compare overall survival (OS) and disease-free survival (DFS) in cervical cancer patients with SCC and AC/ASC in China.

resultsFive thousand four hundred sixty-six patients were enrolled according to the criteria. The 5-year OS and DFS in the SCC group (n = 5251) were higher than those in the AC/ASC group (n = 215). After PSM (1:4), the 5-year OS and DFS in the SCC group were higher than those in the AC/ASC group (72.2% vs 56.9%, p < 0.001, HR = 1.895; 67.6% vs 47.8%, p < 0.001, HR = 2.056). In stage I-IIA2 patients, after PSM (1:4), there was no significant difference in 5-year OS between the SCC group (n = 143) and the AC/ASC group (n = 34) (68.5% vs 67.8%, P = 0.175). However, the 5-year DFS in the SCC group was higher than that in the AC/ASC group (71.0% vs 55.7%, P = 0.045; HR = 2.037, P = 0.033). In stage IIB-IV patients, after PSM (1:4), the 5-year OS and DFS in the SCC group (n = 690) were higher than those in the AC/ASC group (n = 173) (70.7% vs 54.3% P < 0.001 vs 1.940%, P < 0.001 vs 45.8%, p < 0.001).

conclusionsFor stage I-IIA2, there was no significant difference in 5-year survival time, but patients with AC/ASC were more likely to relapse. In the more advanced IIB-IV stage, the oncological outcome of radical radiotherapy and chemotherapy of cervical AC/ASC was worse than that of SCC.
