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

introductionThe process of informed consent before surgery has not been evaluated in Cameroon. We hypothesized that the process of informed consent for patients operated on in the Southwest Region of Cameroon is not appropriate. MATERIALS AND

methodsWe conducted a prospective, cross-sectional study in three health institutions in the Southwest region of Cameroon. A pretested questionnaire was administered to patients in the postoperative period to assess the basic components of the informed consent process. Patient's satisfaction and the overall validity of the process were measured.

resultsWe included 468 consenting patients in this study. Their mean age was 31.41 ± 8.6 y. The majority of patients (58.5%) underwent an elective procedure. The informed consent process was administered on the day of surgery, sometimes on the operative table for 53.4% of patients. Over half of the patients did not receive specific information on the surgical procedure. Though most of them (64.5%) received information about anesthesia, none were ever given the opportunity to choose the type of anesthesia. A total of 268 (57.3%) patients were informed about the potential risks of the surgical and anesthetic procedures. The majority (86.54%) were never informed that the surgery could possibly not yield the expected results. Over 70% of patients never read the consent form, and the overall process was considered fully valid in 1.1% of patients.

conclusionsThough the process of informed consent is now widespread, it is still inadequate as some basic components are not fulfilled and patients' participation in the final decision is poor.
