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

backgroundPoria cocos (Schw.) Wolf or Fuling is one of the top 10 most frequently prescribed herbs in China for the treatment of type 2 diabetes mellitus (T2DM).

objectiveThe purpose of this systematic review is to determine the additional benefit of Fuling formulae use in addition to hypoglycaemic agents for T2DM in randomised clinical trials.

methodsEnglish (5) and Chinese (4) medical databases were searched from their inception to August 2021. RCTs that included Fuling in herbal formulae for T2DM were included. Risk of bias were assessed using the Cochrane Collaboration's procedures. Stata software (13.0) was used for data analysis.

resultsSeventy-three RCTs (6,489 participants) with herbal formulae containing Fuling were included. Most studies were at risk of bias and strength of the evidence were low to moderate. Meta-analysis findings showed that the addition of formulae containing Fuling to hypoglycaemic agent-treatments could benefit people with T2DM by reducing fasting blood glucose (MD -0.82 [-0.93, -0.71]; I2 = 79.6%, P = 0.00), 2-hour postprandial blood glucose (MD-1.15 [-1.31, -0.98], I2 = 80%, P = 0.00) and haemoglobin A1c (MD-0.64 [-0.75, -0.53], I2 = 84.7%, P = 0.00). Adverse events were also significantly lower in the integrative group than in the hypoglycaemic alone group (RR 0.99 [0.93, 1.06], P = 0.87).

conclusionEvidence from this study supports the use of Fuling formulae combined with hypoglycaemic agents for T2DM. The combined therapies appear to be well tolerated. TRAIL REGISTRATION: This review is registered with the PROSPERO international prospective register of systematic reviews (CRD42020214635).
