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
purposeCancer survivors physical function response to exercise programs at the group level is well-established. However, to advance toward a more personalized approach in exercise oncology, a greater understanding of individual response is needed. This study utilized data from a well-established cancer-exercise program to evaluate the heterogeneity of physical function response and explore characteristics of participants who did vs. did not achieve a minimal clinically important difference (MCID).
methodsPhysical function measures (grip strength, 6-min walk test (6MWT), and sit-to-stand) were completed pre/post the 3-month program. Change scores for each participant and the proportion achieving the MCID for each physical function measure were calculated. The independent t-tests, Fisher's exact test, and decision tree analyses were used to explore differences in age, body mass index (BMI), treatment status, exercise session attendance, and baseline value between participants who achieved the MCID vs. those who did not.
resultsParticipants (N = 250) were 55 ± 14 years old, majority female (69.2%), white (84.1%), and diagnosed with breast cancer (36.8%). Change in grip strength ranged from - 42.1 to + 47.0 lb, and 14.8% achieved the MCID. Change in 6MWT ranged from - 151 to + 252 m, and 59% achieved the MCID. Change in sit-to-stand ranged from - 13 to + 20 reps, and 63% achieved the MCID. Baseline grip strength, age, BMI, and exercise session attendance were related to achieving MCID.
conclusionsFindings illustrate wide variability in the magnitude of cancer survivors' physical function response following an exercise program, and that a variety of factors predict response. Further investigation into the biological, behavioral, physiological, and genetic factors will inform tailoring of exercise interventions and programs to maximize the proportion of cancer survivors who can derive clinically meaningful benefits.
