Looking for a word which describes something that doesn't inspire confidence

Question

I am looking for a word which describes results or conclusions which don't inspire confidence because they were reached using poor quality data or a faulty procedure. The feeling I am trying to convey is something that can't be trusted or relied on to be correct.

If the data is of poor quality, the conclusions reached by the study might be inaccurate, misleading, or [insert word here].

Answer 1

"If the data is of poor quality, the conclusions reached by the study might be inaccurate, misleading, or [insert word here]"

The possible choices are: i) untrustworthy ii) unreliable iii) unreproducible iv) biased v) erroneous vi) weak vii) unrealistic viii) flawed ix) unstable (for models based on the data)

Some of these words are taken from the following articles:

1 ) "Why Most Published Research Findings Are False"

http://journals.plos.org/plosmedicine/article?id=10.1371/journal.pmed.0020124

2) "Erroneous laboratory results: what clinicians need to know" https://www.ncbi.nlm.nih.gov/pubmed/17882852

3) "Missing, Biased, and Unrepresentative: The Quantitative Analysis of Multisource Biographical Data"

Answer 2

I think your example sentence might be a bit messed up.

I am looking for a word which describes results or conclusions which don't inspire confidence.

Then you give the example sentence:

If the data is of poor quality, the conclusions reached by the study might be inaccurate, misleading, or [insert word here].

The [insert word here] will modify the "conclusions reached by the study", not the data or results.

The data or results, if it doesn't inspire confidence or make you hesitant to place faith in it, you might call it:

unconvincing
not seeming true or real; not making you believe that something is true
Oxford Living Dictionaries

or maybe "untrustworthy", but really that's very similar to "unreliable", which you already have.
