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

backgroundHealth professionals are often asked if non-pharmacological interventions prolong life. This review aims to evaluate the effects of physical activity, fast-mimicking diet (FMD) and psychological interventions on survival in all cancers.

methodsA systematic review and meta-analysis of randomized controlled trials (RCTs). Only RCTs of physical activity, FMD and psychological interventions (including counselling, cognitive and other psychotherapies) in cancer patients that reported survival outcomes were included. DATA SOURCES: CENTRAL, MEDLINE, Embase, CINAHL, APA PsycINFO, Web of Science, ICTRP and ClinicalTrials.gov from inception to January 2020 were searched without language restrictions. The protocol was prospectively registered at PROSPERO (CRD42019160944).

resultsThirty-one RCTs (9 on physical activity and 22 on psychological interventions) were included in the final analysis after evaluation of 60,207 records from our initial search. No eligible RCT on FMD was reported. RCTs on group psychological interventions (41.9 %) and in patients with breast cancer (38.7 %) were the most common. Most evaluated short-term interventions and in primary or adjuvant settings. Only one of 9 (11 %) RCTs on physical activity and 8 of 22 (36 %) RCTs on psychological interventions were associated with improved overall survival. Only group psychological interventions in breast cancer had adequate number of RCTs to allow a meta-analysis to be performed. It demonstrated a trend towards improved overall survival (HR -0.20, 95 %CI -0.49 to 0.10), particularly in RCTs that evaluated long-term (>6 months) therapies (HR -0.29, 95 %CI -0.59 to 0.01).

conclusionLonger term interventions starting early in the patients' care journey in primary and adjuvant settings have shown the most promise for improving survival. Better designed RCTs including survival outcomes are particularly needed in non-breast cancers.
