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

introductionin sub-Saharan Africa, there is scare published data on cancer in general and gastric cancer in particular.

methodswe conducted a multicenter retrospective analysis of the medical records of patients followed for gastric cancer in 5 hospital departments in the city of Yaoundé (Cameroon) over 6 years.

resultswe recorded a total of 120 patients with a mean age of 53.4 ± 13.7 years. There were 62 females (51.7%). The most common risk factors for gastric cancer in our patients was Helicobacter pylori infection (59 cases, 49.1%). Seventy-six patients (63.3%) consulted within 1 to 6 months of symptoms on set at the forefront of which chronic epigastralgia (74.1%). At endoscopy, the tumor was mostly located at the antrum and was locally advanced or metastatic in 25.8% and 58.4 of cases respectively. Adenocarcinoma was the main histologic type found in 105 (87.5%) cases. Curative treatment could only be implemented in 26.7% of patients. We noted a total of 85 deaths (70.8%) with a mean survival time of 5.91 ± 7.51 months. Survival rate at 3 and 5 years was 10.1% and 4.6%, respectively. On multivariable analysis, variables independently associated with overall survival included: WHO stage 3 performance status (p = 0.042), palpable epigastric mass on examination (p = 0.042), pyloric localization (p = 0.007), and liver metastasis (p = 0.012).

conclusionclinical epidemiology of gastric cancer in our study is comparable to those of other African studies with a predominance of locally advanced/metastatic forms. Prognosis is grim with diagnostic delay behind all of the identified mortality risk factors.
