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

purposeRisk factors for cancer-related cognitive impairment (CRCI) are diverse; neuroimaging instruments are recommended to complement subjective and objective cognitive assessments. This study aimed to evaluate the feasibility of a multidomain assessment protocol for CRCI in gastrointestinal cancer survivors.

methodsTwenty-four patients with gastrointestinal cancer were scheduled for chemotherapy, and 24 healthy controls were recruited. The Functional Assessment of Cancer Therapy-cognitive function (FACT-Cog) was used to assess subjective cognitive functions. Objective cognitive function was assessed using the trail making test, auditory verbal learning test (AVLT), and verbal fluency test. Cerebral hemodynamic changes in the prefrontal cortex were measured using portable functional near-infrared spectroscopy (P-NIRS). Assessments were conducted at baseline and 6-month follow-up.

resultsThirty-eight participants were included in the analysis. There was a statistically significant difference in AVLT-delayed recall (p = 0.002) in the chemotherapy group compared with the healthy control group, but no significant difference in either group for other cognitive assessments. The chemotherapy group exhibited reduced activity in the left frontal pole at 6 months post-treatment compared to baseline (p = 0.018).

conclusionsGastrointestinal cancer survivors who receive chemotherapy may exhibit poorer delayed recall of memory functions than healthy individuals. Monitoring prefrontal cortical hemodynamics using P-NIRS during cognitive tasks is feasible for clinical application and understanding CRCI symptoms. IMPLICATIONS FOR CANCER SURVIVORS: These multidomain assessments are translatable to clinical practice and useful for other cancers. Additionally, the P-NIRS assessments may offer a deeper understanding on the impact of depressive symptoms and declining motivation on the cognitive function of cancer survivors.
