Clinical tools
All 515 tools →Bedside quick-calc cards · share so colleagues can calculate too
Scan to open the same scene workflow — local calc, chart-ready. Short links /r/… for easy sharing.
Turn guidelines into decisions
Enter the patient → risk stratification → thresholds → guideline recommendation, each with class of recommendation, level of evidence and source guideline. Computed locally; decision support for licensed clinicians.
Turn guidelines into pathways
From first contact to disposition, step through the decision tree: red / amber / green stratification → thresholds → guideline recommendation. Each pathway is checked against current guidelines, computed locally — for licensed clinicians.
Chemical Eye Burn Pathway
Immediate copious irrigation to a neutral pH is the priority first aid; grade by corneal opacity/limbal ischemia, alkali burns are worse.
Endometrial Polyp / Intracavitary Lesion Imaging
TVUS feeding-vessel sign suggests a polyp; SIS is the imaging gold standard, hysteroscopy the diagnostic gold standard; differentiate from a submucosal fibroid.
Toxic Shock Syndrome — Management Pathway
Superantigen-mediated; source control + fluid resuscitation + MRSA cover plus clindamycin to suppress toxin, add IVIG for severe/streptococcal disease.
COPD Exacerbation (AECOPD) — Management Pathway
Assess outpatient vs admission; use antibiotics by Anthonisen criteria, systemic steroids and controlled oxygen, with NIV for those who meet criteria.
Acute Limb Ischemia — Management Pathway
Recognize the 6 P's, give immediate heparin + CTA for all, and use Rutherford grade to decide urgency of revascularization vs amputation.
Benign Hysterectomy · Route Selection
Benign indications: vaginal preferred when feasible (fewer complications, faster recovery); not feasible vaginally → laparoscopic (better than open); open only for huge uterus/severe adhesions/malignancy/need for extensive exploration; avoid power morcellation if malignancy suspected (occult sarcoma).
Tumor Lysis Syndrome (TLS) — Management Pathway
Cairo-Bishop laboratory/clinical classification; aggressive hydration, rasburicase for hyperuricemia, manage electrolytes and dialyze as needed.
Septic Arthritis — Management Pathway
Acute hot swollen painful single joint; arthrocentesis is key; after aspiration give empiric antibiotics + joint drainage.
Statistics, ready to run
Fill in your data, get the result: agreement, diagnostic accuracy, survival, meta-analysis, modelling and more. Every tool computes locally in your browser — nothing is uploaded or stored.
Multiple-testing Correction (FDR / Holm)
From a set of p-values, get Bonferroni, Holm (FWER control), Benjamini–Hochberg (FDR) and Benjamini–Yekutieli (FDR under dependence) adjusted q-values and the number significant at each α. Essential for multi-marker/omics/multi-subgroup analyses.
Meta-analysis & Forest Plot
Pool OR or MD across studies with fixed/random-effects models, compute I² and Q heterogeneity and draw a forest plot. Common in systematic reviews.
Statistical Charts (incl. 3D)
Paste data and get a figure: scatter/line/bar/histogram/box plots, plus drag-to-rotate 3D scatter and 3D surface. Supports grouped coloring, titles/axis labels, gridlines; export SVG vectors and 300/600 dpi PNGs. General-purpose plotting ready for paper figures.
Reference Interval
Enter a set of measurements to compute mean, SD, normality test and the P2.5–P97.5 reference interval, producing a reference-interval table ready to drop into a paper.
Normality / Homogeneity of Variance
Assumption checks before t-test or ANOVA: Shapiro–Wilk normality (with Q–Q plot) plus Levene and Bartlett variance-homogeneity tests, to decide parametric vs non-parametric methods. Shapiro–Wilk uses the Royston (1992) algorithm.
t-test / ANOVA
Compare means of two or more groups of a continuous variable: two groups give Student / Welch / paired t-tests, ≥3 groups automatically run one-way ANOVA, with the statistic and p-value.
Paired χ² — McNemar / Cochran's Q
Compare paired binary outcomes: two paired conditions (same subjects, two tests or before/after) use McNemar (with continuity correction and exact binomial); ≥3 paired conditions use Cochran's Q. The ordinary chi-square assumes independence and is wrong for paired data.
RR / OR / NNT Calculator
Enter a 2×2 table to compute relative risk RR, odds ratio OR, absolute risk difference ARD, relative risk reduction RRR and number needed to treat NNT, with 95% CIs for ratios and the risk difference. Common for interpreting cohort/case-control/RCT outcomes.
