Colorectal cancer fecal screening test completion after age 74, sources and outcomes in French program.
Article in World journal of gastrointestinal oncology, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled 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.
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
backgroundElderly patients aged at least 75 years old (Elderly_75), represent 45% of colorectal cancer (CRC) incidence. As others, the French Colorectal Cancer Screening Program (CRCSP) does not include Elderly_75. To date, there is little evidence to justify stopping screening at 74 years of age.
aimTo describe CRC fecal screening test completion after age 74, source (CRCSP/Provider ordered) and outcomes of these tests.
methodsThe study concerned 18704 Elderly_75 residing in eleven French districts (Ain, Doubs, Essonne, Haute-Saone, Hauts-de-Seine, Jura, Seine-Saint-Denis, Territoire-de-Belfort, Val-de-Marne, Val-d'Oise, Yonne), having performed a CRC screening test between January 2008 and December 2017. The tests performed in a circumstance of delayed response to a solicitation (DRS) from the local cancer screening managing center (Managing-Center) were distinguished from the tests non-solicited by the Managing-Center, performed after a recommendation by a General Practitioner (GP) or other provider ordered (RGP). DRS was any test realized by an Elderly_75 following an initial invitation from the Managing-Center with a maximum 24 mo after this invitation. Any Non-DRS test was considered RGP. The outcomes of these tests were described according to the circumstances of test completion.
resultsOf 18995 screening-tests were performed at ages: 75 (83.5%), 76-80 (13.4%) and > 80 (3.1%) years old. Elderly_75 performed the screening test in a circumstance of DRS (71.9%) or RGP (28.1%). The proportion of the tests that could not be analyzed and not restarted was 13.2%. For these unanalyzed tests, the reason was age-related in 78.0% of cases, related to the laboratory's refusal to analyze the test of people aged ≥ 77. Reported colonoscopy completion rate was 81.3%. For those 575 people with reported colonoscopy, no complication was listed. 18.0% of the 366 Elderly_75 with lesions had no anteriority in the CRCSP. The neoplasia (124 Low-risk-polyps, 159 High-risk-polyps, 13 Unspecified-polyps and 70 CRCs) detection rate was 19.3/1000 Elderly_75 screened and the CRC detection rate was 3.7/1000 Elderly_75 screened.
conclusionThe high rate of colonoscopy completion after a positive test and the high proportion of screened lesions observed suggest that the lengthening of the screening period could allow significant detection of CRC and polyps that occur in Elderly_75 excluded from CRCSP.
