Success Rate Estimator

What the Success Rate Estimator does

The Success Rate Estimator answers a narrow question: for a given menopausal or hormonal-health symptom, how much improvement have published trials typically reported for each common treatment over a given stretch of time? You pick one symptom and one time window, and the tool returns a short list of treatments, each with a response-rate range and a one-line description of the outcome measured.

It is a fixed lookup table, not a model or a personalized prediction. The tool does not ask about your age, dose, history, or test results, and it does not run any calculation on your inputs. It simply filters a hand-entered set of trial-average figures to the symptom and duration you selected, then sorts the matches by the top of their reported range. Every row carries the literature it was drawn from, such as NEJM 2003, the STEP and SURMOUNT trials, JAMA 2014, or NAMS position statements.

How to read your result

Read each result as a population average from clinical studies, not a forecast for you. A line like "HRT, 70-90% probability" for hot flashes over 8-16 weeks means trials reported that most participants saw roughly a 70-90% reduction in hot flash frequency in that window - it is not the chance that the treatment works for any one person. The paired description matters: some rows measure frequency reduction, others measure bother, sleep efficiency, cycle restoration, or percent body-weight loss, and those are not interchangeable outcomes.

Use the ranges to compare options and to set rough expectations for a conversation with a prescriber. The estimator lists treatments side by side so you can see, for example, that fezolinetant and SSRIs sit below HRT for hot flashes in the tool's figures, or that response tends to climb from the short to the long window for several symptoms. If a symptom-and-duration pair returns "No data," the table simply has no entry for that combination; try a different duration rather than reading anything into the blank.

None of this substitutes for medical advice. The right choice depends on your personal risk profile, contraindications, and preferences - things this page cannot see. Bring the numbers to a clinician who can weigh them against your situation, and use any provider links only to compare options, not as a recommendation to start a specific treatment.

What the result is based on

The output comes entirely from a fixed table of about two dozen entries hardcoded in the tool. Each entry pairs one symptom (hot flashes, sleep disruption, vaginal dryness, weight loss, mood swings, PCOS cycle regularity, or PCOS hirsutism) with one treatment, one of three duration buckets (short under 8 weeks, medium 8 to 16 weeks, long over 16 weeks), a low and high percentage, a plain-language outcome, and a cited source.

When you make a selection, the tool keeps only the rows matching your symptom and duration and orders them by the higher end of each range. There is no scoring, weighting, or interpolation - what you see is the stored figure, attributed to the study named on that row. Duration buckets that were never populated for a symptom return an empty result rather than an estimate.

The percentages are described in the code as clinical trial averages, and the tool states plainly on-screen that individual response varies significantly and that the results are educational only.

What it cannot tell you

• It ignores everything about you as an individual - age, dose, formulation, how long since menopause, other conditions, and contraindications - so it cannot say whether a treatment is safe or suitable for you, only what trials averaged.
• The figures mix different outcome measures. CBT for hot flashes is a bother reduction, not a frequency reduction; GLP-1 rows report percent body-weight loss; PCOS rows report cycle restoration or Ferriman-Gallwey score change. Comparing the raw percentages across rows can mislead.
• Coverage is uneven and incomplete. Several symptom-and-duration combinations have no entry at all (for instance, sleep disruption only appears in the medium window), and the list of treatments per symptom is short, so an option missing here is not an option ruled out.
• Ranges are population averages from selected trials, not confidence intervals or your personal odds. They carry no information about side effects, cost, how long benefit lasts after stopping, or who dropped out of the studies.
• Source labels are brief (some rows read only "Various" or "Reviews"), so a figure cannot always be traced to a single named study, and the table is a static snapshot that is not automatically updated as new evidence appears.
