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

backgroundThree large randomized controlled trials of fluoxetine for stroke recovery have been performed. We performed an individual patient data meta-analysis (IPDM) on the combined data.

methodsFixed effects meta-analyses were performed on the combined data set, for the primary outcome (modified Rankin scale (mRS) at 6 months), and secondary outcomes common to the individual trials. As a sensitivity analysis, summary statistics from each trial were created and combined.

findingsThe three trials recruited a combined total of 5907 people (mean age 69.5 years (SD 12.3), 2256 (38%) females, 2-15 days post-stroke) from Australia, New Zealand, United Kingdom, Sweden, and Vietnam; and randomized them to fluoxetine 20 mg daily or matching placebo for 6 months. Data on 5833 (98.75%) were available at 6 months. The adjusted ordinal comparison of mRS was similar in the two groups (common OR 0.96, 95% CI 0.87 to 1.05, p = 0.37). There were no statistically significant interactions between the minimization variables (baseline probability of being alive and independent at 6 months, time to treatment, motor deficit, or aphasia) and pre-specified subgroups (including age, pathological type, inability to assess mood, proxy or patient consent, baseline depression, country). Fluoxetine increased seizure risk (2.64% vs 1.8%, p = 0.03), falls with injury (6.26% vs 4.51%, p = 0.03), fractures (3.15% vs 1.39%, p < 0.0001) and hyponatremia (1.22% vs 0.61%, p = 0.01) but reduced new depression (10.05% vs 13.42%, p < 0.0001). At 12 months, there was no difference in adjusted mRS (n = 5760; common OR 0.98, 95% CI 0.89 to 1.07). Sensitivity analyses gave the same results.

interpretationFluoxetine 20 mg daily for 6 months did not improve functional recovery. It increased seizures, falls with injury, and bone fractures but reduced depression frequency at 6 months.
